One of the things I love most about Star Wars is how many archetypes and inspirations it throws in. There’s Akira Kurosawa, Flash Gordon serials, The Searchers, second world war films, Metropolis and Casablanca, and those are just the ones I can think of off the top of my head.
By the way, I stole this random point from the BFI classics book for Star Wars by Will Brooker, and if anyone’s looking for a good book/analysis on the film, it’s a must.
