One of the most overlooked elements of any film is the ridiculous amount of props that have been used to dress each set, making the world of the movie feel more lived-in and visually engrossing.
Your average scene will contain dozens of items that have been carefully placed throughout the set - or costumes that have been painstakingly hand-crafted - in order to evoke a certain mood or atmosphere, but once shooting is over and the film is ready to screen for audiences, what happens to all of these potentially valuable items?
It really depends on the prop in question: some are auctioned off, some are saved for sequels, and others are donated to museums or public displays, and very occasionally, some are stolen by the actors and taken home to use as ornaments.
Theft is generally, y'know, frowned upon, and realistically, the actors have no valid claim to this stuff, but hell, if you were forced to swing a hammer around for six months, wear a prosthetic penis, or dress up in spandex all day, you might also feel like you deserved to take home a souvenir. And these cheeky rascals did just that.
