Only three people have officially portrayed Walt Disney in filmed productions. The first person to do so was Roy E. Disney, Walt's nephew. He played his uncle in an internal film used at the studio in the late 1980's.
In 1993, Walt Disney Television produced a biopic based on Annette Funicello's life. This time, Len Cariou played Walt Disney.
The most recent actor to portray Mr. Disney was Tom Hanks, who put his spin on the world famous entertainer in Saving Mr. Banks.
Two lesser known films recently portrayed Walt Disney as a young man. In As Dreamers Do, he was portrayed by Olan Rogers.
While the other film entitled Walt Before Mickey features Eddie Kaye Thomas as Walt.
Of course, nobody can quite replace the "Mousetro" himself.
