Featuring a tense script and superb acting, Dial M for Murder (1954) marked a departure from Hitchcock’s man-on-the-run suspense movies in more ways than one. Faithfully adapted from the successful Broadway play, Hitchcock opened up the action by shooting his legendary marriage and murder thriller in 3D, using the stereoscopic Natural Vision method. Sadly, the format fell out of favour just before the film’s original theatrical release, but thanks to Park Circus, Dial M for Murder – 3D now returns to the big screen in a gorgeous, newly restored and remastered version. Below, Paul O’Connell revisits the Hitchcock classic in 3D, released in selected UK cinemas on 26 July 2013, and available on Blu-ray by Warner Home Video.
