Great Alfred Hitchcock movie! Some iffy stuff though with Guy and his wife at the beginning. He is getting divorced because she has been having affairs with other men and she is pregnant. But it's a brief moment and really only mentioned once. The violence is very minimum also!
There is one scene in particular involving glasses that everyone who's seen the movie knows what I'm talking about that is truly genius. Another classic Hitchcock film, keeping you on your toes most of the time. The premise is interesting, and Robert Walker's performance is especially entertaining.
