A Double Life [1947]

Anthony John is an actor whose life is strongly influenced by the characters he plays. When he's playing comedy, he's the most enjoyable person in the world, but when he's playing drama, he's impossible to be around. it's terrible to be around him. That's why his wife Brita divorced him: although she loves him and still works with him, she couldn't stand to live with him anymore. So when Anthony has the role of Othello, he devotes himself entirely to the part, but it soon overwhelms him; with each day, Othello's murderous jealousy fills his mind more and more.
