The liberal political group said it will kick off the campaign with a sold-out gala in New York on Aug. 24 called "10 Weeks: Don't Get Mad, Get Even!"
The campaign -- scheduled to run through Election Day -- will feature TV ads created by such filmmakers as Rob Reiner, Darren Aronofsky and Allison Anders, with appearances by Hollywood stars including Matt Damon, Scarlett Johanssen, Kevin Bacon and Rebecca Romijn.
MoveOn PAC said it would announce a new initiative each week intended to support Kerry's campaign. The first will be promoted by an ad called "Register and Vote," written and directed by Benny Boom -- who has directed music videos for P.Diddy, Nelly and Kelly Rowland, and commercials for Reebok and Footlocker.
Other commercials lined up for the campaign include: "The Mistake," directed by Reiner; "Tommy," written and directed by Linklater; "Cheney Is Not on Our Side," written and directed by Harrelson; and "American Opinions," written and directed by John Sayles, and featuring the voice of Martin Sheen.
