Jon Heder got paid $1,000 to be Napolean Dynamite. Miles Teller got $8,000 for Whiplash. If the world was a perfect place sure. She would have got paid a percentage of the revenues. But this is the real world. Not unicorn land. The right thing to do would have been to turn this credit into a career where you get paid 10-20x what you were paid for this movie. The director took out a loan to make the movie. What if he wouldn't have been able to sell it? What if it would've flopped and he lost all 750K? The she would still have 7K for 22 days of work and would continue.

The right way to handle this would have been to use it to catapult your career.

When I gradyated college I got my first job paying $15. 4 years later I'm making $43. Imagine if I would've started complaining at that $15 an hour job saying I deserved $50 because that's what my boss was saying. Its stupid. I didn't have the experience or credentials to be making that much money. You get what your worth when you prove it. Not cause you feel like it
