Here's one of those famous on set naps that I was telling you about. I bet it's way easier for a little person to find a good place to nap on set than it is for someone of normal size. Sure, many other things are harder for them, but you can curl up and get cozy nearly anywhere, so it's a trade off. Warwick Davis looks so young in this picture. It brings a tear to my eye. Oh, how time passes.
A common thing to do to people who are napping on set is to prank them. Imagine the crew of the Jackass movie. They were doing the craziest pranks to each other. The only solace was that those pranks would be part of the movie too. At least the prank wouldn't go in vain.
