It was on this day in 1928 that Walt Disney Studios showed Plane Crazy, a single reel silent cartoon featuring Mickey Mouse. However the Mouse failed to pick up a distributer. Later that year Disney tried again with Steamboat Willie to wild success.
So, while this is actually Mickey’s birthday (In case the math is difficult he turned 89 today.), this particular film wasn’t seen until the next year as the fourth of the now voluminous adventures of Mickey Mouse.
