And while we might suspend our disbelief and forget that there are real people acting behind the screen, the movie productions are very much real life to the cast and crew. And things do get real behind the scenes, from forgetting you are wearing robotic makeup and heading out for lunch, to catching nasty infections. It seems like the actors and the crew behind have seen it all throughout the years, and it's nice to see some manage to have fun with it.
