1. The original title was Planet Moron, but was later dropped for Spaceballs. It should be noted that Spaceballs is a combination of “space” and “screwball”, as in the type of comedy filmmaker Mel Brooks is known for making.
2. George Lucas was fine with Brooks making Spaceballs just as long as there was no merchandising of the characters. Now we know why I can’t find a Barf talking stuffed toy.
3. In order to really cement that approval from Lucas, Brooks used LucasFilm for their $5 million post-production work.
4. Rick Moranis (Lord Dark Helmet) says that Brooks was interested in a sequel, which Moranis thought should be called Spaceballs III: The Search for Spaceballs II.
5. Brooks produced and directed a 13 episode Spaceballs: The Animated Series in 2005. The only cast members to return for the project were Daphne Zuniga (Princess Vespa), Dot Matrix (Joan Rivers), and Brooks himself.
6. Tom Cruise and Tom Hanks turned down the lead role of Lone Starr, so Brooks went to non-Tom Bill Pullman.
7. Some members of the cast thought that the green screen used for special effects would ruin their eyesight, leading to many wearing sunglasses between takes for protection.
8. Dark Helmet playing with his toys was not in the script. Brooks came up with the idea and Moranis ad-libbed the scene.
9. Michael Winslow saved production around $1,000 by doing all of his own sound effects in his scene.
10. There is a novelization of Spaceballs written for kids/teens. The author? R.L. Stine.
