Other mistake: When Austin, MiniMe and Foxxy are in Nigel's Mini, MiniMe is communicating to them with written notes. When he writes the first note to Austin, Austin reads it with the written words facing the camera. He is reading the back of the page where no words exist. Also, the words are upside down when facing the camera. In slo-mo, we can see the hand-off of the paper from Mini Me to Austin and how the front, top written on side of the paper ends up facing the camera and upside down. There is no way that Austin can read what is on the page. The paper is not thin enough to be read through as one other person has claimed. Foxy receives a note from Mini Me and we cannot read through the paper that is handed her.
Other mistake: In the scene where Dr Evil and Goldmember are in the submarine, they get two henchmen to bring out Nigel Powers from his cell. Just before Nigel explains to the henchmen how he's going to beat them up, if you look through the glass face of the submarine just behind Nigel's head, you can see a fake fish dangling past on a string.
Other mistake: As Goldmember skates out onto the dancefloor, the black woman in gold behind him has a few problems rollerskating. She doesn't quite keep in time with the music like everyone else, and stumbles after everyone raises their knee. The woman directly behind her seems to bump into her.
