Disclaimer: This analysis assumes you’ve seen Dial M for Murder, hence there will be spoilers a-plenty.
Tony and Margot Wendice (Ray Milland and Grace Kelly) appear to be a happily married English couple. Tony is an ex-tennis champ who’s settled into a life of quiet domesticity. Margot is a beautiful socialite with a massive fortune. However, there’s trouble in paradise. Margot’s been having an affair with an American crime writer named Mark (Robert Cummings) and is currently being blackmailed over it. Little does she know that the blackmailer is Tony himself, who’s been aware of her infidelity for a long time and is ready to do something in retaliation.
A gold-digger at heart, Tony wants to make sure Margot doesn’t leave him with her fortune in tow—so what better way to stop her than murder? He blackmails a former college chum named C.A. Swann (Anthony Dawson) into strangling Margot and then making it look like a botched burglary. This is to be the perfect crime, timed to the second. However, a faulty wristwatch and a conveniently placed pair of scissors prevent the murder, and Tony has to improvise to make sure he can get Margot out of the way and ward off the persistent Inspector Hubbard (John Williams), so that nothing stands between him and that sweet, sweet money.
It’s no secret that Alfred Hitchcock’s film adaptation of Frederick Knott’s hit play is often considered underwhelming. Hitchcock himself dismissed Dial M for Murder as a rote assignment he had to get through before moving onto Rear Window. What’s worse, he was forced by Warner Bros. to shoot Dial M in the cumbersome 3D process, only for it to be shown flat by the time it was ready for exhibition.
Critics are mixed in their reactions. They praise Hitchcock’s creative use of 3D, which avoids gimmicky pop-out shots and instead favors a subtle sense of depth through careful mise-en-scene. However, the film’s characters and story tend to be criticized as one-dimensional, and Hitchcock’s reluctance to open up this one-room thriller often earns him the old “canned theater” accusation hurled at so many stage to screen adaptations.
I take issue with both of these complaints, though I didn’t always. When I first saw Dial M, it left me cold. The plot was clever but the characters seemed little more than cogs in a well-oiled suspense machine. However, multiple viewings and further reading have changed my perspective. Hitchcock not only took a very talky play and made it thoroughly cinematic through inspired camerawork and editing, but he also took a rather simple stage melodrama and turned it into something altogether more complicated when you look beyond the surface.
The lack of “ventilation” in Hitchcock’s Dial M was an intentional choice on the part of the director. Hitchcock thought that you should never go out of your way to artificially open up a play because the confinement of setting was what gave the source material its dramatic power. While we get a few moments outside the apartment, it’s by and large the central setting of the movie. Hitchcock even prevents location fatigue by using a variety of angles to film the apartment, making us intimate with every nook and cranny.


Certain key plot points are also milked for a more cinematic form of suspense. Tony’s theft of the latchkey is presented as a fake love game with Margot, shot in close-up, rather than in the play, where he sends Margot into another room so he can snatch it undisturbed.

Hitchcock does the same with Tony’s planting the key on the staircase, where he shoots the moment in long-shot while Tony speaks with Margot at the threshold. Some might say the long shot is itself “stagey,” because God forbid we not have cuts every other second or shove the camera into some odd location for novelty all the time. In truth, Hitchcock was actually respecting the intelligence of the audience– he knew we would get what Tony was doing without an unnecessary insert. Call the film talky all you want, but it’s certainly more than a filmed stage play.
Dial M for Murder is often described as “mechanical.” Critics Sheldon Hall and Tim Brayton call it a “machine” in their respective analyses. And it is undoubtedly a story with more appeal to the head than the heart. I don’t think it’s controversial to say that when you look at all of Frederick Knott’s stage thrillers (Dial M for Murder, Write Me a Murder, Wait Until Dark), he was more a “plot” guy than a “character” guy. Even he would admit as much in a 1966 interview with William Glover in which he discussed his writing process: “You know what you want your characters to do before you figure out why they do it. Then you get the most important scenes first. It isn’t chronologically orderly, but it is effective.” There’s nothing inherently wrong with this approach to writing. However, it’s clear where Knott’s interests lie. His work focuses less on complicated characterization and theme, and more on plot construction and twists.
Now most people, including Hitchcock himself, claim the movie version of Dial M is just the play with minimal changes. One critic who challenged this notion was Peter Bordonaro, who wrote a fantastic piece titled “Dial M for Murder: A play by Frederick Knott/A film by Alfred Hitchcock” for Sight and Sound back in the 1970s.
Bordonaro went through Knott’s play and Hitchcock’s film in-depth, showing the subtle but numerous differences between them, particularly in the presentation of the characters. He argues that Knott’s play is a straightforward melodrama where the characters all have equally straightforward motivations. Tony’s just a gold-digger. Margot has erred, but ultimately wants to do right by her marriage vows with no temptation to err again. Inspector Hubbard and Max—who was renamed Mark in the movie— are the heroes who save the day.
Bordonaro claims that Hitchcock complicates the play through a variety of methods. Firstly, there is a greater emphasis on sexual intrigue. Hitchcock endows keys and handbags with a Freudian significance not necessarily emphasized in the original, making Tony’s intrusion into Margot’s purse a bit more suggestive. And as academic Sarah Street points out, he’s not just stealing a key—he’s invaded a private space where she keeps things like, oh, love letters. And he’s also deprived her of a source of power, in a sense—remember, keys are one of Hitchcock’s favorite phallic symbols. And do I need to say anything about Hitchcock and handbags?
The marital bedroom becomes more pronounced too, with the door almost constantly open and scenes originally set in other places relocated there, such as when Mark discovers the payoff money. Even Margot’s bed becomes a center piece in the last scene, when it’s moved to the living room the day before Margot’s execution.

This detail was in the play, but Hitchcock milks its presence for all its Freudian worth, with the characters using the bed frame as a coat rack and then having Margot seated on it, rather than on the couch, during her return to the apartment.
The heightened thematic importance of sexual relationships is most apparent when comparing the opening moments of the play with the movie’s prologue. In the play, we start with Max telling Margot about his work as a crime author, sharing what the stock motives are for his criminal characters. This reveals that Knott’s main interest is in the mechanics of the criminal plot and how it all goes wrong. The adultery is just a vehicle to get us there.



In the movie, we get a wordless montage showing how the Wendices seem to exist in a state of marital bliss, only for the appearance of Mark to dispel that notion. Hitchcock emphasizes Mark the adulterer over Mark the crime novelist, and Margot’s shifty glance over the newspaper makes her appear less than innocent. Even the brief glimpse we get of Tony makes him seem guileless, complete with him spilling salt on the table and throwing it over his shoulder for good measure. In these few seconds, he seems almost bumbling—a far cry from what we learn once he invites Swann over for a chat. So overall, this prologue emphasizes both the main love triangle and how no one in this trio is who they seem to be.

Margot’s characterization is generally more complex than people realize. In both versions, she’s a pretty passive character, a pawn in the great competition between the men in the story. However, Hitchcock’s film does a little more with her than the source material. In the play, she might have been an adulteress, but the opening scene makes it clear that she’s sworn off her affair. Their meeting was even prompted by Max, who called the Wendices up during his visit to the UK. When Max says he’d originally hoped to save Margot from “her jealous husband,” Margot smilingly replies, “Only to find that husband and wife were very happy, thank you very much.”

Not so in the movie, where their first scene together begins with them kissing passionately. Whatever Margot says or how her conscience bugs her about it, it’s clear this affair isn’t over or at the very least, conquering her feelings will be an uphill battle. An uncharitable perspective might argue she’s stringing the two men along (and I have seen people online argue that), though Kelly plays Margot with enough inner conflict that I doubt she is doing so.
If Margot is made to appear somewhat less morally perfect in the film, Bordonaro also feels Tony is made more superficially appealing, at least in the first half. Knott’s Tony is pretty unlikable, even outside of the whole murder thing: he makes snotty comments about Max’s TV writing career, casually lies even when it isn’t necessary for his plan, and is sleazy enough to pawn his wife’s personal letters off to snooping reporters after she’s been sentenced to death.
Ever the master of giving the audience memorable villains, Hitchcock eliminated these traits, resulting in a far more urbane and smooth operator. He’s the villain you love to hate and hate to love, and his evil plotting is pretty fascinating to behold. Hitchcock’s Tony is also better at concealing his wicked nature to the other characters. He’s courteous towards Mark and even engages in flirty little games with Margot. And yet in spite of his deceit and ruthlessness, Tony’s a charismatic guy the audience enjoys watching. Guess who’s not?
The play’s Max Halliday cuts a heroic figure. He tries to be a good sport about Margot ending their affair and he gallantly helps Hubbard come to the rescue in the second half with his super-writer skills. We are clearly supposed to admire him. In the movie, Hitchcock cast actual charisma void Robert Cummings. He’s like the human equivalent of white bread and to be honest, it’s hard to see what Margot finds so irresistible about him in terms of personality or sex appeal. Even when he comes in to save the day, he still comes off as a dud, especially next to the brilliant Inspector Hubbard.
You might assume this is poor casting (or maybe just I do– I admit I’m allergic to Robert Cummings, in this movie and in Hitchcock’s earlier collaboration with him, Saboteur), but considering how Hitchcock often complicates the morality of his characters, I agree with Bordonaro that this may well have been intentional. We have a would-be murderer who’s a charmer, and a so-called hero who’s an annoying bore.

As much as I enjoyed Bordonaro’s article, I don’t agree with all of it, particularly his idea that Tony might actually harbor genuine affection for Margot. Bordonaro uses Tony’s anxious facial expression during the attempted killing as evidence for his having conflicted feelings about Margot, maybe even second thoughts about murdering her, but I always saw it as Tony being anxious over the killing going wrong. It’s still his bank account and life on the line.

I also have a hard time believing Tony is conflicted about killing Margot, not just because he tried killing her once, but because the second attempt is crueler than the first. It involves prolonged psychological torture and public humiliation as well as death. And because we know Margot, for all her faults, never wanted to hurt Tony, this causes a serious dip in his villainous charm. However, I do agree that Tony is—or rather was— emotionally invested in his marriage, just not for the same reasons Bordonaro gives.

Going back to the sexual intrigue angle, you could argue Tony sees himself as emasculated by Margot. Tony has a massive ego and a competitive edge, both of which were formerly nourished by his athletic superstardom. It is implied Margot fell in love with Tony due to his glamorous image. Margot’s money was the major attraction for Tony, but considering Tony’s ego, the starstruck adoration of a beautiful woman was probably a good bonus.
Yet, it didn’t take long for Margot to try changing Tony. The things that likely made Tony so alluring—his athletic profession and his world traveling—became liabilities once they were living together because A) travel is exhausting and B) travel probably cuts into Margot’s busy social life. Hence, Tony needs to quit tennis and get a real job selling sports equipment. Tony constantly shows bitterness over this through a variety of passive-aggressive comments about “playing husband.”
I imagine selling sports equipment can hardly supply the same rush as being on the court. So, when Tony commits to the elaborate murder plot, he takes an unusual relish in the entire process, beyond just a desire for money or revenge. The murder scheme is probably the most fun he’s had since he got married. It’s a sublimation for all he lost when he quit tennis.

Hitchcock even emphasizes this visually by having the compositions during the blackmail scene resemble a tennis court, with Tony and Swann going back and forth, often divided by the furniture or other visual elements. This same back and forth applies to his square-off against Mark and Hubbard in the second half.
I must re-iterate that none of this means Margot deserves to be murdered, but it does mean this marriage would have had problems even if Tony wasn’t a homicidal sociopath. Margot, like Tony, can be very selfish (though to a decidedly different degree, I think we should note). The two of them are also basically liars, hiding all their unhappiness behind superficial manners and smiles, a recipe for disaster that under more optimal conditions might normally end in hiring a marriage counselor or a divorce lawyer, and not C.A. Swann.
With all this in mind, it’s fascinating how Dial M, like so many Hitchcock films, constantly tests audience loyalties. Our sympathy shifts from character to character depending on the scenario. Of course, as Sheldon Hall points out in his analysis, though we identify with several of the characters from scene to scene, Hitchcock isn’t insistent that we necessarily empathize with them. Everyone here has issues that give depth to the conflict, but we never become truly intimate with them as we do with the lead characters in Hitchcock’s best films. Still, I think Kelly has a few heartbreaking moments, particularly in her final scene, where she looks like she’s been incarcerated in hell. She’s come a long way from being the vivacious woman she was in the first act.

In a twisted way, Dial M’s resolution is a little bittersweet. We know Tony deserves to be caught and it’s satisfying to see Hubbard entrap him, but he’s also the most fun character. He even accepts his defeat with a hilarious shrug, toasting the inspector and offering everyone a drink. Margot breaks down, perhaps from the overwhelming stress of the situation, perhaps because part of her did truly love Tony. She’ll be scarred by this nightmare for a long time, with only sentient wood block Mark to comfort her. All of this complicates our reactions to the finale, even if we’re happy that Margot is now safe and Hubbard gets a moment to smooth his mustache.


In his interview with Hitchcock, filmmaker Francois Truffaut said of Dial M for Murder that it was a movie which grew on him the more he saw it. I’m in the same boat. I’ve even come to think Dial M might be Hitchcock’s most underrated work, or at the very least, one that competes strongly with Rope or The Trouble with Harry for that honor. Its virtues are magnified upon further acquaintance and I hope if you weren’t impressed with the film before, you’re willing to give it another chance now.
