At the very end of the movie, when Agent Perabo returns to finally go to the movies with the guard who is still waiting there: as she approaches the theater, the camera shows the marquee above her; it says "The Rocky and Bullwinkle Movie". In a second, as the two go into the theater, the camera pans up to show the same marquee, this time called "The Adventures of Rocky and Bullwinkle". Maybe the first shot was filmed when they planned to release the movie under that name, and the later filmed after the move to the release name?
