'Star Wars: Episode VI - Return of the Jedi' (1983)
Domestic box office: $309,306,177 | Worldwide box office: $475,106,177 | Six years after "Star Wars" made its debut, the original series came to a close with "Return of the Jedi." For Lucas, it was a welcome ending. "There hasn't really been one day in the last 10 years that I haven't had to wake up in the morning and say, 'God, I've got to worry about this movie,'" Lucas said at the time. "Now I feel as if this huge weight has been lifted off my shoulders ... If I had to do it all over again, I'd have to think about it, especially if I knew what I was going to have to give up in order to get it."
