Frantic would definitely qualify. I'm always surprised when people say they haven't seen many Hitchcock films. He's made some of, IMO, the greatest movies ever made. If you haven't seen any of the following you really owe it to yourself to watch: Notorious. Shadow of a Doubt (one of his greatest), Strangers on a Train, Dial 'M' for Murder, Rear Window, To Catch a Thief. the 1956 The Man Who Knew too Much, Vertigo, Psycho, The Birds, and especially North by Northwest. Each of those are great.
