Actor and director George Clooney, an MPTF board member and co-chair of the fundraising campaign, announced the donation Tuesday.
The campaign was created to build the endowment and support the charitable operations of the industry's charity.
"Steven Spielberg, Jeffrey Katzenberg and David Geffen are each legendary for their philanthropy and individually have made immeasurable impact on charities and organizations ranging from arts and culture, health care, education, film preservation and social services in our Hollywood community and around the nation," Clooney said in a statement.
"And now for them to make this unified commitment to MPTF only adds to that incredible record of generosity."
