If you've ever wished you could belly up to the bar at the Mos Eisley Cantina, hold a beer in all three of your hands, and sip them gently through your insect-like proboscis, then put on your party pants and ready your passport: this is your big chance!

"Star Wars: Episode VII" director J. J. Abrams announced today the "Force for Change" campaign, a charitable initiative by Disney and Lucasfilm in collaboration with Bad Robot, benefiting Unicef. Fans who support the cause won't just be making a difference, they'll also be eligible to win an incredible prize: a trip for two to London, where the winner and a guest will be given a behind-the-scenes tour of the Star Wars set, and an on-screen cameo in the movie, in full wardrobe and makeup.

For more information and to enter, visit Omaze.com/StarWars. May the Force be with you, and may your proboscis be bigger than you ever dared to dream.
