The original release did not include any of Robin Williams' scenes. It was re-released just before Popeye (1980) premiered, with his scenes included, and advertised as "Robin Williams' Movie Debut."
All scenes featuring Robin Williams were added to the film sometime after its theatrical premiere, to capitalize on his success in the TV series "Mork & Mindy"). According to British critic Barry Norman however it was Williams' growing fame that caused him to seek to have his scenes in this movie removed.
