Here's a treat for you Star Wars fans, the original screen test for actors Harrison Ford and Mark Hamill.
The actors had never met before their audition. Hamill said neither he nor Ford had any idea what the movie was about.
When Hamill asked the director what kind of movie they were making George Lucas said "let's just do it, we'll talk about that later. we never did talk about it later, we just did it."
