On the heels of the original trailers for The Empire Strikes Back and Return of the Jedi (when it was still titled "Revenge") comes another relic from a galaxy far, far away: a never-before-seen blooper reel from 1977's Star Wars, unearthed by Lucasfilm editor and author J.W Rinzler.

It's not side-splittingly funny, but it is amusing to watch Peter Cushing flub Grand Moff Tarkin's threat to Princess Leia, Alec Guinness' delivery derailed by a Wookiee arm, and Storm Troopers fumbling their way through debris.

Note: The first part of the reel is silent; the sound doesn't kick in until about 48 seconds in.
