Producing a film requires a wide variety of contracts, including actor, director and producer agreements. Movies have the potential to generate millions of dollars, so it's essential to know who will share in that income. Some filmmakers, such as George Lucas, have been fortunate enough to strike deals allowing them to participate substantially in their films' back-end profits. The result: George Lucas became an incredibly wealthy man because of the "Star Wars" franchise he created. Many filmmakers don't like getting bogged down in the legal aspects of producing their films, but a little extra time and attention can mean the difference between a decent deal and a "Star Wars" sized deal.
