Cary Grant gives one of his finest performances in Alfred Hitchcock’s seminal tale of mistaken identity. Roger Thornhill, a suave, self-satisfied ad-exec, is mistaken for a spy after a mix-up at a New York hotel bar – without a chance to explain, Thornhill ends up pursued by enemy agents set on smuggling government secrets out of the country. His attempts to flee take him on a heart-stopping cross-country chase, with only his wits (and assistance from a mysterious and beautiful double agent) to keep him alive.
