Other mistake: Near the end of the closing credits, when the Warner Bros. Copyright appears, you'll see the very first word "All" spelled incorrectly as "Al" in "All material is protected by Copyright Laws of the United States and other countries throughout the world." (01:26:40)
Other mistake: When Bang (the green Monstar) calls Michael Jordan Baldy, he's standing to Michael's left. But, when Michael looks up and says Baldy, he's looking to his right, not at the one who said it.
Other mistake: The Phoenix Suns/New York Knicks game (with the Knicks as the home team) is being played at the Los Angeles Sports Arena.
Other mistake: In the movie the planet that the aliens live on is called Moron Mountain but on the scene selection screen, it says Moon Mountain.
Suggested correction: Both of these people were also credited in the film for their appearance, so this wouldn't be trivia.
