Donations to attend the fundraiser range from $1,000 to $5,000. The gathering is being billed as "A Massachusetts Evening," in reference to the fact that Affleck, Damon and Krasinski are also from the state.

Those who have already given to Warren include Barbra Streisand, Steve Bing, and Lorraine and Sid Sheinberg, musician Herb Alpert, television writer Victor Fresco, producer Jim Michaels, actress Nancy Stephens, television producer Marcia Carsey, actress Shira Piven, Hans Zimmer, Ron Howard and Will Ferrell.

Republicans, meanwhile, have sought to portray Warren as an "elitist" for mingling with the Hollywood crowd.
