"Star Wars" fans to get chance at "Episode VII" cameo

Ever wanted to be in a "Star Wars" film? Here's your chance.

Director J.J. Abrams is giving fans a shot at a cameo in "Star Wars: Episode VII" in the name of a good cause.

Disney, Lucasfilm and Bad Robot have teamed up for a campaign to raise funds for UNICEF. Abrams announced the initiative in a video from the set of the movie in Abu Dhabi.

For every $10 donation at Omaze.com/StarWars, contributors will become eligible to appear in the film when it shoots in London.

"The 'Star Wars' fans are some of the most passionate and committed folks around the globe," Abrams said in a statement. "We're thrilled to offer a chance to come behind the scenes as our VIP guests and be in 'Star Wars: Episode VII.' We're even more excited that by participating in this campaign, 'Star Wars' fans will be helping children around the world through our collaboration with UNICEF Innovation Labs and projects."

The campaign began just after midnight Wednesday and runs until 11:59 p.m. PT on July 18. You can find out more at StarWars.com/ForceForChange.

The cast of "Episode VII" was revealed in April, and Adam Driver, Oscar Isaac and Daisy Ridley are among the new cast members. Disney will release the film in December 2015.
