Could it be that Luke Skywalker is actually moonlighting as a Stormtrooper, and not hiding in some faraway corner of the galaxy? In an effort to promote charitable organization Omaze and a Force for Change, Mark Hamill dressed up as a Stormtrooper and mingled with fans on the streets of Los Angeles. His tomfoolery was captured in the clip above.

The last time Hamill was disguised as a Stormtrooper, it was back when he helped rescue Princess Leia in Star Wars: A New Hope, which also saw the death of Obi-Wan. It was a pivotal moment in the Star Wars universe, and helped lead to the eventual victory in Return of the Jedi.

As part of the Omaze promotion, a few lucky donors will win the chance to meet the cast of Star Wars: The Force Awakens, and attend the movie’s premiere in a few weeks. If you want a chance to enter, you can follow the link right here. All it takes is $10; all money donated will help support the work of 15 different charities.

Check out the video above. Not only does it help promote a good cause, but it’s hilarious to see Mark Hamill interact with unsuspecting bystanders as a Stormtrooper.
