Hands down, one of the best Hitchcock films ever made (and his personal favorite film)...and what's not to like about this film? Thrilling shots and chases, lots of dark humor, more than you'll likely ever seen in any other Hitchcock film, the chemistry between ALL of the actors, etc. BTW, this was re-released in theaters at Cinemarks in the U.S. a few years ago...I HIGHLY recommend seeing it once that way, the pacing is almost perfect, you would never have even noticed the time passing, and then all of the sudden, its over!
BTW, I see a few sour-grapes reviews in this thread...just ignore them, the criticisms are entirely without merit and overlook the many many many great things about this film, which I put in my top 20 easily.
