Visible crew/equipment: In the opening shot, as the camera moves down the building, in the windows you can clearly see the cameraman & camera on the hoist/crane. (00:01:00)

Continuity mistake: When Ryan is talking to Page in her office about Cindy's medical condition she hands him a white coffee mug with black stripes. In a close-up, the mug has changed to a white one with a square picture on one side (the one Page took). It subsequently changes back again. (00:25:40)
Continuity mistake: When Andy is standing by the table, Lindsay comes over telling him that she wants to make out, but he's all disgusted because she has BBQ sauce all over her face. For the first few angles of the scene, the BBQ sauce is on the corner of her mouth, and on the side of her face a little. But in one angle, it is ALL over her mouth. Then it comes back to the previous angles and it is back in the corner of her mouth again. (00:49:15)
Suggested correction: They keep adding more sauce intentionally for comedy.
Continuity mistake: When Matt Dillon asks Liv Tyler what her favorite thing is, he starts to raise his mug to his mouth with his right hand. Then the shot changes, and suddenly the mug is in his left hand.
Continuity mistake: When Derek Zoolander is being interviewed by Mugatu for the first time, when Mugatu's assistant brings him his drink and Mugatu spits it out you can see the drink all over the top of his mouth. Then you see him right away after that and it is gone. (00:27:10)

Continuity mistake: When Jimmy and the rest of the kids are standing on the balcony, Jimmy asks Goddard to activate his binoscope so they can get a better view of the arena. Goddard then extends his eyes into tubes and raises them. However, in the next shot, his eyes are raised but not extended into tubes yet. They also take on a different shape than in the previous shot. (01:04:53)
Continuity mistake: During Buffalo Bob's first appearance, he's holding a rake with both hands. In the next shot, he's holding it with just one hand.
Continuity mistake: When Chaucer is introducing William at the end of the movie, he stands on the arms between the chairs of Prince Edward and the lady, a foot on each arm. When it cuts to a side view showing William's father to the Prince, Chaucer is no longer in between the chairs. Not to mention the fact that the Prince is looking at the railing (where Chaucer just was). The very next shot, he is back between the chairs. (02:03:05)
