While Jon Stewart and Stephen Colbert went straight for the funny bone in their promo last week for the "Star Wars VII" charity fundraiser, director J.J. Abrams is appealing directly to our geeky hearts. 

The 48-year-old has posted yet another video urging people to donate to the "Force for Change" children's charity and in the process potentially win a walk-on role in the new film. While the reveal of the new (and somewhat battered) X-Wing Starfighter during the video is cool enough, Abrams and Disney have also sweetened the grand prize. 

“We are so grateful for the support that the fans from over 119 countries have shown for Force for Change," said Abrams in a statement. "As we close this final week, we’ve added an additional prize that allows the fans the opportunity to see the movie early as a thank you for supporting such a great cause as UNICEF’s innovative, lifesaving work for children.”

While Disney has yet to reveal the current fundraising totals for the nearly nine-week campaign, officials did share that more than $1 million was brought in on the first day alone. To throw down your $10 entry before the July 25 deadline, hit the official campaign site here.
