11 Thrilling Facts About Dial M for Murder
In 1953 Alfred Hitchcock was looking for a new project after a film he’d been developing fell through. Sensing a need to go back to his safe space of murderous thrillers, he opted to adapt a stage play that had already proved to be a hit on British television. Though he had no particular attachment to the project, Dial M for Murder would ultimately become one of Hitchcock’s best-known—and best-loved—classics.
From the film’s use of 3D to the debut of Grace Kelly in Hitchcock’s filmography to a pivotal murder sequence that made the director lose weight from stress, here are 11 facts about Dial M for Murder.
1. IT’S BASED ON A STAGE PLAY.
Dial M for Murder is, in terms of locations and number of characters, a relatively sparse film that barely leaves its primary set. This is because it was based on a stage play by Frederick Knott, which premiered as a BBC TV special in 1952 and later opened at London’s Westminster Theater and, eventually, Broadway. After seeing the BBC production, producer Sir Alexander Korda purchased the rights to make the film version, and later sold them to Warner Bros. for $75,000.
2. ALFRED HITCHCOCK THOUGHT HE WAS “COASTING” WHEN HE MADE THE FILM.
By 1953, when Dial M for Murder arrived at Warner Bros., Hitchcock was developing a project called The Bramble Bush, the story of a man who steals another man’s passport, only to find out that the original owner is wanted for murder. Hitchcock wrestled with the story for a while, but was never satisfied with it. When Dial M for Murder landed at the studio, Hitchcock knew the play had been a hit, and opted to direct it. As he later told fellow director François Truffaut, he found the film to be “coasting, playing it safe,” as he was already known as a thriller filmmaker.
3. IT’S HITCHCOCK’S ONLY 3D FILM.
In the early 1950s, the 3D movie craze was raging, and Warner Bros. was eager to pair it with the fame of Hitchcock. So, the director was ordered to use the process on Dial M for Murder. This meant Hitchcock had to work with the giant cameras necessary for the process, but there was also a trade-off that makes the film fascinating—even in 2D. In order to make the film look appropriately interesting in 3D, Hitchcock added a pit into the floor of the set, so the camera could move at lower angles and captures objects like lamps in the foreground. As a result, the film looks like no other Hitchcock ever shot, particularly for the infamous scissors murder that’s the film's thrilling centerpiece. Unfortunately, by the time Dial M for Murder was released in 1954, the 3D fad was dying out, so the film was shown in 2D at most screenings.
4. IT WAS HITCHCOCK’S FIRST FILM WITH GRACE KELLY.
Of all of the iconic blonde stars Hitchcock cast in his films, the most famous is almost undoubtedly Grace Kelly, the actress-turned-princess who first joined him for this film. Hitchcock once described Kelly as a "rare thing in movies ... fit for any leading-lady part,” and it was said he had the easiest working relationship with her of any star. They worked so well together that they went on to make two more films, Rear Window in 1954 and To Catch a Thief in 1955.
5. IT TAKES PLACE ALMOST ENTIRELY INDOORS.
Because Dial M for Murder is based on a stage play, the original script had very little in the way of outdoor set pieces. Hitchcock wanted to keep it that way, as he later explained to Truffaut:
“I’ve got a theory on the way they make pictures based on stage plays; they did it with silent pictures, too. Many filmmakers would take a stage play and say, ‘I’m going to make this into a film.’ Then they would begin to ‘open it up.’ In other words, on the stage it was all confined to one set, and the idea was to do something that would take it away from the confined stage setting.”
Hitchcock wanted to keep the confinement intact, so almost all of the action in the film takes place indoors, largely in the Wendices' apartment. This adds to the intimacy and tension.
6. HITCHCOCK PERSONALLY CHOSE EVERY PROP.
Hitchcock was always known as a meticulous director obsessed with detail, but on Dial M for Murder he was particularly detail-oriented, in part because the 3D cameras were going to capture objects in a way his other films hadn’t. As a result, he selected all of the objects in the Wendice apartment himself, and even had a giant false telephone dial made for the famous “M” close-up in the title sequence.
7. KELLY’S WARDROBE GROWS DARKER ON PURPOSE.
Hitchcock’s exacting eye also led to an elaborate “color experiment” to portray the psychological condition of Kelly’s character. As the film begins, the colors she wears are all very bright, suggesting a happy life in which she doesn’t suspect anything is wrong. As the film grows darker for her, to the point that she’s framed for murder, the wardrobe grows darker and “more somber,” as Hitchcock put it.
8. KELLY WON A PARTICULAR WARDROBE ARGUMENT.
For the scene in which Swann (Anthony Dawson) attempts to murder Margot (Kelly) by strangling her (until she manages to stab him with a pair of scissors), Hitchcock had another exacting wardrobe request. He had an elegant velvet robe made for Kelly, hoping to create interesting textural effects as the lights and shadows played off the fabric while she fought for her life. Kelly reasoned that, since Margot was alone in the apartment (as far as she knew) and was only getting out of bed to answer the phone, she wouldn’t bother to put on a robe.
“I said I wouldn't put on anything at all, that I'd just get up and go to the phone in my nightgown. And [Hitchcock] admitted that was better, and that's the way it was done,” Kelly later recalled.
9. HITCHCOCK WAS SO NERVOUS ABOUT THE PIVOTAL SCENE THAT HE LOST WEIGHT.
Dial M for Murder was shot in just 36 days, but the director took special care with one scene in particular: the murder sequence in which Margot stabs Swann with the scissors. Not only was it a key scene in the film, but it was also a moment that required particular care to make the 3D effects work. Hitchcock agonized over the scene to such a degree that he apparently lost 20 pounds during filming.
"This is nicely done but there wasn't enough gleam to the scissors, and a murder without gleaming scissors is like asparagus without the hollandaise sauce—tasteless,” he reportedly said after one take.
10. HITCHCOCK MAKES HIS CAMEO IN A PHOTOGRAPH.
Hitchcock became known throughout his career for making cameos in his films, ranging from the very subtle (you can see his silhouette in neon outside the window in Rope) to the more elaborate (missing the bus in the opening sequence of North by Northwest). In Dial M for Murder, his cameo falls somewhere in between. He appears in a class reunion photo in the Wendice apartment, seated at a banquet table among other men.
11. IT’S BEEN REMADE FOUR TIMES.
Dial M for Murder was a film adaptation of a stage play that had also already been adapted for television in Britain, and it proved popular enough that four more adaptations followed. In 1958, NBC broadcast a Hallmark Hall of Fame production, in which both Anthony Dawson and John Williams returned to play Swann and Chief Inspector Hubbard, respectively. A 1967 ABC television production of the play co-starred Laurence Harvey and Diane Cilento. A television movie starring Angie Dickinson and Christopher Plummer was produced in 1981, and in 1998 the play served as the inspiration for the film A Perfect Murder, starring Michael Douglas and Gwyneth Paltrow.
