Raised in Switzerland, Kreuger attended college in London and New York. He began appearing in films in 1943; thanks to his classic Aryan looks and Continental accent he was frequently cast as young Nazis, though he occasionally got romantic leads. Rugged and blond, he became very popular with women, and for a time he was 20th Century-Fox's #3 male pinup. He might have become a star, but he was never cast in suitably central roles. Kreuger became an American citizen in 1944. During the '50s he appeared primarily in European films, then later returned to Hollywood in supporting roles. He last appeared onscreen in 1967, but went on to occasional work on TV. He became a millionaire in Hollywood real estate transactions.
