There’s a lot of planning that goes in to making a movie. It relies upon cooperation between dozens of different departments, which can sometimes mean hundreds of people. And despite having a daily call sheet that tells everyone where they need to be and when they need to be there, productions can still go off the rails. So when tension is high, it can be nice to have a team of funny people around to lighten the mood. And for a comedian, the best time to crack a joke is when everything’s going wrong.
