Henry Koster went on to do numerous musicals and family comedies during the late 1930s and early 1940s, with Durbin, Betty Grable, and other musical stars of the era. He and Joe Pasternak filmed a successful screen test for Universal's newest singing star, Gloria Jean, but Koster would never direct one of her features; when Pasternak left Universal for Metro-Goldwyn-Mayer in June 1941, Koster went with him. Ironically, despite Koster's escape from Nazi Germany, when the United States entered World War II Koster was considered an enemy alien and had to stay in his house in the evening. Actor Charles Laughton would visit Koster and play chess with him.
