Hans Walter Conrad Veidt was a German-British actor. He attracted early attention for his roles in the films Different from the Others (1919), The Cabinet of Dr. Caligari (1920), and The Man Who Laughs (1928). After a successful career in German silent films, where he was one of the best-paid stars of UFA, Veidt and his new Jewish wife Ilona Prager left Germany in 1933 after the Nazis came to power. The couple settled in Britain, where he took citizenship in 1939. Veidt subsequently appeared in many British films, including The Thief of Bagdad (1940). After immigrating to the United States around 1941, he was cast as Major Strasser in Casablanca (1942), his last film role to be released during his lifetime.

Different from the Others is a silent German melodramatic film produced during the Weimar Republic. It was first released in 1919 and stars Conrad Veidt and Reinhold Schünzel. It was directed by Richard Oswald, and the story co-written by Oswald and Magnus Hirschfeld, who also had a small part in the film and partially funded the production through his Institute for Sexual Science. The film was intended as a polemic against the then-current laws under Germany's Paragraph 175, which made homosexuality a criminal offense. It was one of the first sympathetic portrayals of gay men in cinema.
