It’s not a prequel! It’s not a remake! It’s a “premake” — a re-imaging of a favorite film as the product of a bygone era. In this case it’s Star Wars Episode V: The Empire Strikes Back, rejiggered from footage from old serials, b-movies, and TV shows. StarWars.com has a full list of the source material for the film, remixed by youtube user “Whoiseyevan.”
Creating a video like this is an admirable skill, not unlike DJs that are adept at pop song mash-ups. I certainly couldn’t think of all the individual shots from old films that it would take to create something that recalls a completely different film. While I don’t agree that Leslie Nielsen is the 1950s version of Mark Hamill, their retro Chewbacca is pretty spot on.
