The Mask

The oversized teeth on the Mask character were originally to be used only during silent scenes, but Jim Carrey learned to talk while wearing them to make his character that much more wacky.

The detective says that the bank was robbed by a guy in a green mask, but the surveillance tape is black and white. He could have connected this crime to the events of the previous night, where there were eyewitnesses.

When all the credits have finished some jazz drumming is heard. Then the familiar sounds of The Mask are heard saying "Yo-ho-ho-ho" (in a very drawn voice) then the sound of The Mask spinning away is heard straight after.

There is a deleted scene in which the hood rats harassed Stanley and took his watch prior to entering his apartment building and after getting the mask from the polluted river, this explains why he punished the hoodlums and why they asked for the time, it also clarifies when Stanley's landlady asks him if he knows what time it is and he answers that he actually does not.
