Ub Iwerks
In animation, MGM purchased the rights in 1930 to distribute a series of cartoons that starred a character named Flip the Frog, produced by Ub Iwerks. The first cartoon in this series (entitled "Fiddlesticks") was the first sound cartoon to be produced in two-color Technicolor. In 1933, Ub Iwerks canceled the unsuccessful Flip the Frog series and MGM began to distribute its second series of cartoons, starring a character named Willie Whopper, that was also produced by Ub Iwerks.
