10 Hilarious Movie Gags Everyone Missed

9. Jim Carrey's Secret Cameo As Fire Marshall Bill - Liar Liar

Jim Carrey is an absolute force of nature in his hit comedy Liar Liar, commanding the screen at every single moment - well, almost.

You see, in addition to playing protagonist Fletcher Reede, Carrey makes a sneaky cameo appearance as Fire Marshall Bill, a character he previously portrayed in the sketch show In Living Color.

Just as Fletcher is wheeled off to the ambulance in one of the film's final scenes, "Bill" can be seen hanging out in the background, mugging incessantly with Carrey's distinctly rubber-faced expression - and kitted out with teeth the size of piano keys for good measure.

But hidden in plain sight as it is, it's so incredibly easy to miss, and some 20+ years after the movie's release, most viewers still have no idea about it.
