"Premakes" The Empire Strikes Back (1950)

From The Great Geek Manual:

One Youtube user envisions what Star Wars would have looked like if it had been a 3D movie made in the fifties. The trailer is astonishingly authentic, mainly because it’s cobbled together from actual fifties movies like Flash Gordon, The Phantom Planet, and Buck Rogers. It may well be the most impressive Star Wars tribute video I’ve ever seen.
