Helmut Dantine was a film actor remembered for playing many Nazis in thriller films of the 1940s. The Vienna-born actor appeared uncredited in Casablanca early in his career. Dantine's father was the head of the Austrian railway system. As a young man, Dantine became involved in an anti-Nazi movement in Vienna. In 1938, when he was 21 years old, the Nazis took over Austria during the Anschluss. Dantine was rounded up, with hundreds of other enemies of the Third Reich, and imprisoned in a Nazi concentration camp outside Vienna. Three months later, using their influence, his parents got his release and immediately sent him to California to live with a friend. Both his parents would later die in a Nazi concentration camp. He began his U.S. acting career at the Pasadena Playhouse, where he was spotted by a talent scout and signed to a Warner Bros. contract. Dantine spent the early 1940s there, appearing in International Squadron with Ronald Reagan, Casablanca, Edge of Darkness, Mission to Moscow, Northern Pursuit, Passage to Marseille, The Mask of Dimitrios, Hotel Berlin, and Escape in the Desert.
