A hapless New York advertising executive is mistaken for a government agent by a group of foreign spies, and is pursued across the country while he looks for a way to survive. Roger Thornhill finds himself thrust into the world of spies when he is mistaken for a man by the name of George Kaplan. Foreign spy Philip Vandamm and his henchman Leonard try to eliminate him but when Thornhill tries to make sense of the case, he is framed for murder. Now on the run from the police, he manages to board the 20th Century Limited bound for Chicago where he meets a beautiful blond, Eve Kendall, who helps him to evade the authorities. His world is turned upside down yet again when he learns that Eve isn't the innocent bystander he thought she was. Not all is as it seems however, leading to a dramatic rescue and escape at the top of Mt. Rushmore.
There is a famous scene that is a prime example of tension building and the use of different camera angles help to heighten the tension, the scene is so good that a certain shot of it was actually the poster for the film.

Cary Grant was initially reluctant to accept the role of Roger Thornhill since at 55 he was much older than the character.The day before the scene where Thornhill is hidden in an upper berth was to be filmed,Cary Grant took a look at the set which had been built and told Alfred Hitchcock that it had been constructed sloppily and would not do for the film. Hitchcock trusted Grant's judgment so completely that he ordered the set rebuilt to better standards without ever checking the situation for himself. Cary Grant got $450,000 for this movie - a substantial amount for the time - plus a percentage of the gross profits. He also received $315,000 in penalty fees for having to stay nine weeks past the time his contract called for.

The final chase scene was not shot on Mt. Rushmore; Alfred Hitchcock couldn't gain permission to shoot an attempted murder on a national monument. The scene was shot in the studio on a replica of Mt. Rushmore. Everything is shot carefully, so as to avoid associating the faces of the monument with the violence. 

Director Cameo- Alfred Hitchcock:  Hitchcock arrives at a bus stop (during the opening credits) but gets there a second too late and the door is closed in his face. He misses the bus.
