By the 1930s, he was a popular matinee idol and was acting in films. From Germany, where he had worked with the likes of Veit Harlan, he moved to United States when World War II broke out and acted in a number of films, starting with Enemy Agent in 1940. In Hollywood, he made his screen debut in “Enemy Agent” (1940), followed by “Ski Patrol” (1940). He was usually cast as Continental lovers, anti-Nazi Germans or refugees. In the 1950s, he returned to Europe and acted in German films. He was married twice. His first wife was Cornelia Maria Twilt (1921–1930). He was married to Dutch actress Marianne van Dam until his death (1933–1975). Dorn suffered from phlebitis, requiring surgery and causing a number of strokes. After an accident on stage, he retired in 1955 and spent the next 20 years of his life in his home in California. He died of a heart attack in Los Angeles.
