Continuing in the proud tradition of celebrities who disguise themselves in cosplay at San Diego Comic-Con, SFGate reports Mark Hamill hid among fans on the convention floor donned as a stormtrooper. But while Luke Skywalker dressed up as an Imperial stormtrooper over 40 years ago, Hamill took a modern approach by disguising as a First Order stormtrooper from the recent Disney ?Star Wars? films. And yes, he joked about Leia?s infamous ?Aren?t you a little short for a stormtrooper?? line in his Instagram post.
