Bad guys aren't always loveable characters, but Star Wars is a definite exception. Everybody loves Vader and the Empire has a very cool design aesthetic going on – Stormtroopers, Tie Fighters, Royal Guards, Imperial Walkers – I'll stop there, oh wait – Star Destroyers. With the exception of the Tie Fighter PC game many years ago and no doubt a few other games, comics and books the emphasis has always been on the good guys in Star Wars, which means without delving deep into canon we never get to really know the Empire. Perhaps not knowing about them adds to their coolness, although after seeing the short film below they seem a whole lot more cool.
A legend by the name of Paul Johnson has spent four years drawing and animating an epic Star Wars space battle from the Empire's perspective. If you're a Star Wars fan you need to watch it right now.
