Remember that Stormtrooper that bumped his head on a door in A New Hope? The blooper managed to make its way into the final cut of the 1977 Star Wars film, and the film’s 2004 re-release embraced the gaffe by adding an audible sound effect to accompany the on-screen gag. Aside from the near-entirety of Terminator 2: Judgement Day, the head-bumping Stormtrooper is one of cinema’s most notorious goofs, but the identity of who actually played that Stormtrooper remains a mystery.
