25 Things You Didn't Know About The Mask

5. Peanut Butter Was Used To Get Milo To Perform On-Set...And It's Visible In The Movie

Stanley memorably has a dream where Tina, dressed in a ludicrously sexy costume, approaches Stanley and starts licking his face - and especially his ear - frantically.

He soon wakes up to realise it was actually his dog Milo licking his face, but eagle-eyed viewers might notice a handy set prop that actually sneaked its way into the movie.

On Stanley's bedside table, there's an open jar of peanut butter with a knife sticking out of it.

It's a common technique for dog handlers to use peanut butter to entice dogs to perform on-set, and clearly, that was the case here: they presumably slathered Carrey's face in the creamy stuff and let the canine go at it.

Whether it was left in the shot as a mistake or a deliberate nod remains to be seen, but it's clear as day in the Blu-ray release of the film.
