May 15, 1928 –
Plane Crazy was the first animated cartoon to feature Mickey Mouse as well as Minnie Mouse (Mickey’s girlfriend). The short was co-directed by Walt Disney and Ub Iwerks.
Iwerks was also the main animator for this short and reportedly spent six weeks working on it. Hugh Harman and Rudolf Ising were credited for assisting him; these two had already signed their contracts with Charles Mintz, but he was still in the process of forming his new studio and so for the time being they were still employed by Disney.
The cartoon was pretty much produced in secret, as Walt Disney was still contracted to the Oswald the Lucky Rabbit series for Universal.
