This video from Vanity Fair (wait, that can't be right.... ok, it's really from Vanity Fair. I didn't know that was a thing that could happen) shows roughly how much money everyone that has worked on a $200 million blockbuster would make. I can't believe the cat made like 10 times what the intimidating bouncer at the nightclub made. That's probably racist.
Basically what I learned from this is that there's good money to be made being like a Key Grip, or a makeup artist. Sure you have to live with the nightmare that is not knowing when your next job will be but it beats digging ditches for a living. Unless you're the lead ditch digger for a movie, I hear those guys make bank.
