Mark Hamill Goes Undercover as Stormtrooper to Greet ‘Star Wars’ Fans on Hollywood Blvd. (Video)

Mark Hamill disguised himself as a stormtrooper and took to Hollywood Boulevard to tell fans that this is their last chance to win tickets for the premiere of “Star Wars: The Force Awakens.”

“Star Wars” has teamed up with Omaze to benefit 15 different charities chosen by the cast and filmmakers. It furthers the mission of “Star Wars: Force for Change,” a campaign to inspire people to make a positive change in the world.

“The last time anybody saw me in a stormtrooper outfit was when we rescued the princess off the Death Star.” said Hamill, as he geared up for his adventure. “I couldn’t be more proud of everyone in the ‘Star Wars’ family. Your support has been absolutely fantastic, and I for one can’t wait for the premiere.”

While walking down Hollywood Boulevard, Hamill encountered other “Star Wars” cast members, such as Darth Vader, and met hardcore fans of Hamill himself. Of course, they didn’t know he was under the mask.

“Mark Hamilton,” a woman responded when Hamill asked her whom she would like to meet from the cast. “I’ve been in love with that man.”

Asking unknowing pedestrians who their favorite “Star Wars” characters are, the actor who reprises his role as Luke Skywalker in the “The Force Awakens” gets himself involved in a lightsaber war while spreading the word about the contest.
