UPA Productions - Columbia Studios

Some who left Disney Studios around the time of the studio's 1941 strike later established United Productions of America (UPA), a studio for cartoons distributed by Columbia, and known for simplified, stylized drawings of human characters in the Jolly Frolics cartoon series, such as Gerald McBoing-Boing (first seen in the cartoon Gerald McBoing-Boing (1951)) and the near-sighted Mister Magoo (with voice by Jim Backus).

Mister Magoo's first cartoon was Ragtime Bear (1949) - also in the same series of Jolly Frolics cartoons. The first of the Mister Magoo series of cartoons was Spellbound Hound (1950). Mister Magoo starred in UPA's first feature-length cartoon film, the 76-minute 1001 Arabian Nights (1959).
