WASHINGTON (CNN) - Matt Damon and Ben Affleck are teaming up for a new project, but this one probably won't lead to an Oscar.
The two actors are part of a new effort from MoveOn.org to create a television ad in support of Barack Obama's bid for the White House. The liberal group, which endorsed the Illinois senator last month, is asking its 3.2 million members to create a 30 second campaign commercial that "shows what inspires them about the senator's candidacy."
Damon and Affleck, along with film director Oliver Stone and singer John Legend, are among the panel of judges.
"After eight years of President Bush campaigning on fear and war, people are feeling hopeful again. They're eager to talk about what inspires them about our country - and Senator Obama leading it,” Eli Pariser, Executive Director of MoveOn said. “Since creative and grassroots energy has helped power Barack Obama’s campaign from the start, this contest is a great way to deliver that message of hope to voters in Pennsylvania and across the nation.”
In a statement, Affleck said the competition is "a chance for everyone, from aspiring filmmakers to armchair pundits, to raise their voices to put Obama over the top."
MoveOn says it will announce the winner before the crucial Pennsylvania primary which takes place early in April. It says the winning ad will air on national television but has not yet decided when. The winner will also win a gift certificate for $20,000 in video equipment.
The group held a similar competition in 2004, asking members then to create a "Bush in 30 Seconds" campaign ad. The organization received 1,500 entries in that contest.
