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.
Continuity mistake: When Cappy von Trumpet says "it's almost as if there's a mole in the white house", it shows a mole. Then, after Cappy says "yes, sir" we see a view of the president's desk and the mole isn't anywhere to be seen. Then, when Agent Sympathy says "ROCKY AND BULLWINKLE!" in a very excited voice, we see the mole surprised.
