Easter egg: From the main menu go to Special features, you will see the options Commentary, Yearbook & Trailers. Press DOWN once more and a white horse type logo appears on the top right of the screen. Select that and you get the music video to Rob Zombie's song "Never gonna stop".
Rollerball (2002)
1 easter egg
Directed by: John McTiernan
Starring: Jean Reno, Chris Klein, Rebecca Romijn, LL Cool J
Other mistake: In the scene after Jonathan and Aurora have sex in the gym, Jonathan gets on the company plane. You'll notice that he grows a massive beard overnight. Then, in the next scene, it's semi-shaved.
Trivia: Rollerball is referred to as "sports entertainment," which is the current euphemism for professional wrestling.
