Trivia: Another Stiller family member made an appearance in this movie. Ben's sister is seen when Derek is first introduced to everyone in Hansels pad where they will hide out. She is the redhead seen to give the 'peace' sign.
Continuity mistake: When Zoolander, Hansel and Matilda are drinking the tea near the end of the movie, the "steam" in Zoolander's cup keeps on changing to from overflowing the cup, to half way down and none. This is without ever refilling his cup. He can even be seen blowing some of the steam out and next thing it's full again. (00:58:00)
