You may have seen this classic Alfred Hitchcock movie already — but probably not the way that he intended.
In response to this post on when 3D movies are worth the extra cost and hassle and when they're not, commenter Michael Walsh reminded us of the famed director's first (and last) foray into the world of 3D filmmaking during a studio fad for the technique in 1952:
For a real interesting item, though, try Alfred Hitchcock's only 3D film, Dial M for Murder. Its a standard 3-act, one set 5-character stage play. No goblins flying in your face, no swooping moves, instead you inhabit the constricted space of the apartment. The only time 3D is crucial is one shot is one that truly heightens the drama. Leave it to the Master to find the one unique way to use a new technology.
But, although it was filmed for 3D, by the time the movie was released audiences were pretty much over the nonstop stream of things flying up of their screens and for the most part, it was shown in 2D instead. Which led Hitchcock to remark of 3D: "It's a nine-day wonder, and I came in on the ninth day."
