I've never seen Hitchcock's "Dial M For Murder." I've been really itching to, though, and lucky for me, it comes on television tonight. Mainly, I'd just like to know if it's "safe" to watch. My biggest fear is that it'll be a pan and scan version. It was released in 1954, which, if I'm not mistaken, is right around the time Hollywood started shooting films in widescreen, so I imagine it could go either way. I checked IMDB, and sure enough, they list it as 1.37:1. They're not always 100% reliable, though, so I'd really appreciate confirmation from someone in-the-know. Also, the IMDB lists the film's cinematographic process as "3-D." What exactly do they mean by this? Was this shot in 3-D originally and viewed with a pair of silly glasses? Exactly what implications does this have on viewing the film at home? Thanks.
