The Adventures of Rocky & Bullwinkle (2000)

Revealing mistake: In the scene where Rocky and Bullwinkle are walking through the university with Kenan and Kel (right before they come across the anti-moose protest), Kel's right arm passes through Rocky's left several times.

Audio problem: At the end when Boris and Natasha are drinking from glasses, they throw their glasses up in victory and we hear the glasses shattering. But in the long shot, there's no sign of broken glass anywhere.

Continuity mistake: In the scene when the FBI agent is in the TV tower early on in the film, you see her put the FBI Identification card thing back into her 'mobile phone holder' in her bag. Then you see the guards charging up the stairs. Then the shot goes back to the FBI agent. She hasn't put her ID card thing inside her bag yet, she is still holding it.

Trivia: When Boris Badenov falls off the water tower and gets out of the hospital the sign says"J.Ward". Jay Ward was the creator of Rocky and Bullwinkle.

Minnie Mogul: I can't sign a contract that will help three ruthless villains take over the world. I just can't.
Fearless Leader, Boris, and Natasha: Why not?
Minnie: My pen's out of ink.

Fearless Leader: How many times in the past have they stood between me and my dreams of glory? How many times have they foiled my plans with their bungling interference?
Boris: Er... 28?
Fearless Leader: Quiet, idiot.

Rocky: I knew we shouldn't have left him! We haven't been apart in thirty-five years.
