Son of Flubber is a 1963 American science fiction comedy fim directed by Robert Stevenson and produced by Walt Disney Productions. It is the sequel to The Absent-Minded Professor (1961) and the first sequel to a Disney film. Fred MacMurray reprises his role from the previous film as Ned Brainard, a scientist who has perfected a high-bouncing substance, Flubber ("flying rubber"), that can levitate an automobile and cause athletes to bounce into the sky. In addition to MacMurray, Nancy Olson, Keenan Wynn, Ed Wynn, Elliott Reid, and Tommy Kirk also co-star, reprising their roles from the previous film.

Released on January 16, 1963, the film was shot in black and white, but a colorized version was released on VHS in 1997.
