From MySpace Celebrity:

Reflecting Barack's call for change, the film features over 50 of the biggest stars in Hollywood revealing how they plan to personally participate in keeping America strong, proud and green. The clip will be presented to our new President during his inaugural celebration.

"There's an assumption that this one man is going to take on his new job full-time and somehow wave a magic wand of change, and I don't believe that to be true," Ashton tells Reuters. "I think that we have to be the leaders, and that's not celebrities--I think that we as citizens have to be leaders of the movement that we want to create."
