(KGTV) - Was the iconic 'Steamboat Willie' the very first Mickey Mouse cartoon ever made?
Walt Disney's first Mickey Mouse film was called 'Plane Crazy.' It was a silent film shown to a test audience in 1928. But distributors weren't excited about it, so it wasn't released to the public.
But after 'Steamboat Willie' became a huge hit, 'Plane Crazy' was finally released as the 4th Mickey Mouse film in 1929.
'Steamboat Willie' was the first Mickey Mouse cartoon with sound.
