1 plot hole
Directed by: Brian Levant
Starring: Stephen Baldwin, Mark Addy, Jane Krakowski, Kristen Johnston
Continuity mistake: In the beginning of the movie when the letters of "Univershell" rotate around the Universal-logo globe, Earth is pictured as preglacial one-continent planet. When it's pictured as a background looking from out of the UFO it's the regular spaceview of Earth.
Fred Flintstone: Your eyes are like two big blue eyes.
Trivia: Harvey Korman also did the voice of The Great Gazoo, as well as several other minor characters in the original animated TV show The Flintstones.
