It's not easy breaking into the entertainment business in Hollywood. It either take a lot of hard work, or you simply just know somebody. Here's a great short film called The Come Up, that follows an ambitious production assistant who "pulls off a daring heist on a Hollywood film set in a scheme right out of the movies, all to impress the industry’s biggest producer while (of course) pitching his screenplay in the process."
The movie was directed by Kirk Sullivan and it turned out really entertaining, and I'm sure you'll enjoy it! Thanks to Film School Rejects for the find!
