Grace Kelly also stars in Hitchcock's next film, Dial M for Murder. This is the story of an ex-tennis pro who wants to kill his wife to get his hands on her money. He blackmails one of his old college friends in order to make it look as if the friend has committed the murder. He thinks he has planned the perfect murder, but has he? Watch Grace Kelly's costumes in this film. Hitchcock had her wearing progressive darker outfits as the film goes on. And his cameo comes early in the film because he knew that people were watching for his cameo and he did not want them to miss the story. So he always tried to put his appearance in as early as possible. He can be seen in the college reunion photograph.
Hitchcock was not done with Grace Kelly yet. The next year he starred her and Cary Grant in his film, To Catch a Thief. Cary plays a retired cat burglar who is hired to find the thief who is committing jewel thefts similiar to his own style. His nickname was the cat and Hitchcock uses subliminal cat images at the beginning of the film whenever Grant comes on screen. Hitchcock's cameo is about ten minutes into the film. He is seen sitting next to Grant on a bus. Also note the name of the boat that Grant and Kelly are riding in early in the film. The boat is name "Maquis Mouse".
