If you're wondering what inspired Baz Luhrmann's use of 3D in his theatrical and tricksy Great Gatsby, look no further. Luhrmann saw Dial M For Murder "many years ago" and noted Hitchcock's use of 3D to crank up the human drama of "actors standing in a room doing an eight-page scene". The original 3D game-changer is back on the big screen in July and has a new stereoscopic poster to let everyone know. Note how the tagline isn't "Hitchcock phones it in!" here.
It may not be quite as exalted as Vertigo and Psycho, but with its nasty brand of double-dealing and Hitch's sure sense of the macabre, Dial M endures as one of the best of his straight-up thrillers. Like Rope, with its one-room set-up, it's adapted from a stage play - also by its screenwriter Frederick Knott - and it afforded the Master the opportunity to experiment with a new filmmaking format.
Its protagonists, Tony and Margot Wendice (Grace Kelly and Ray Milland) and American crime-writer Mark Halliday (Robert Cummings), share a tightly-plotted tale of betrayal, adultery, murder and suspicious telephone calls. If you haven't seen how it all pans out, you can catch Dial M For Murder in UK cinemas, restored and re-released in modern 3D, from July 26.
