The 1950 film Harvey involves Elwood P. Dowd (Played by James Stewart) having an invisible rabbit friend, but the actors took this further both off-camera and by Stewart himself in his commitment to the role. Firstly, as a joke, the cast and crew would often set a chair for the title character at lunch and order him something to eat. Secondly, it was at the suggestion of Stewart himself that director Henry Koster changed many shots to make them wider so that "Harvey" would be in the frame. No wonder the character became so real to the audience. Stay tuned!
