In 1938, The Katzenjammer Kids were adapted by Metro-Goldwyn-Mayer, becoming the studio's first self-produced series of theatrical cartoon short subjects, directed by William Hanna, Bob Allen and Friz Freleng. The series was unsuccessful, ending after one year and a total of 15 cartoons. Following that cancellation, Freleng returned to Warner Bros., where he had earlier been an animation director. The Captain was voiced by Billy Bletcher, and John Silver was voiced by Mel Blanc.
