North by Northwest

What if everyone around you was suddenly convinced that you were a spy? This classic from master director Alfred Hitchcock stars Cary Grant as an advertising executive who looks a little too much like someone else and is forced to go on the lam (helped along by Eva Marie Saint). Hitchcock's sure-handed comic drama pits Grant against a crop duster and lands him in a fight for his life on Mount Rushmore -- a true cliffhanger if ever there was one.
