'Star Wars' Quiz: Test Your Knowledge As The Movies Turn One Year Older

Most of us know a bit about the storied legacy of the original "Star Wars" trilogy, a series that raked in more than $2.7 billion worldwide after its grosses are adjusted for inflation. But how much can you truly recall about the illustrious sci-fi series that introduced us to Jedis, the Force and a philosophical little green man who taught us just as much as he did Luke Skywalker?

All three movies turn one year older this week. Saturday, May 25, marks the 30th anniversary of 1983's "Return of the Jedi" and the 36th commemoration of 1977's "A New Hope." Tuesday, May 21, was the 33rd anniversary of "The Empire Strikes Back." In celebration, we've got an exclusive excerpt from the book "The Making Of 'Star Wars: Return of the Jedi,'" a list of 30 things we wouldn't have without "Star Wars" and, as mentioned, a quiz that will put even the most loyal fans to the test.
