What it's about: In a galaxy far, far away, Luke Skywalker gets tangled up with a Jedi knight, pilot Han Solo, a giant bear thing called a wookiee, and two droids — all in order to save the galaxy and rescue Princess Leia from the clutches of Darth Vader. The first "Star Wars" movie established one of the most popular franchises of all time and took science fiction movies mainstream again.
