The names who have signed up as co-chairs and sponsors have expanded considerably since they first went out last month.
Co-chairs, those who have written checks for $25,000 or have committed to raise that amount, include George Lucas, Katie McGrath and J.J. Abrams, Annette Bening and Warren Beatty, Steve Bing, Heather Thomas and Skip Brittenham, Carole Bayer Sager and Bob Daly, Sarah and Ariel Emanuel, Richard Buckley and Tom Ford, Stanley Gold, Berry Gordy, Tom Gores, Cindy and Alan Horn, Jimmy Iovine, Jena and Michael King, Erik Hyman and Max Mutchnick, Van Fletcher and Skip Paul, Michele and Rob Reiner, Lynda and Stewart Resnick, Lorraine and Sid Sheinberg, Steve Tisch, Laura and Casey Wasserman and Susan Harris and Paul Junger Witt.
Also contributing is the Walt Disney Co., which also has given to the campaign of Brown's rival, Meg Whitman. Bob Iger, the CEO of Disney, has previously given to Brown.
Sponsors, or those who have agreed to write checks for $10,000 or raise that amount, include Leslie Mann and Judd Apatow, Joyce Klein and Gerald Breslauer, Megan and Peter Chernin, Susan and Jonathan Dolgen, Rita Wilson and Tom Hanks, Stacey Snider and Gary Jones, Sherry Lansing, Lyn and Norman Lear, Melissa Blake and Robert Orci, Mo Ostin, Norman Pattiz and Marilyn and John Wells.
Also listed as a sponsor is George L. Rose and Activision. Rose is the chief public policy officer of the game publisher. Interestingly, on Election Day, Brown's office will be defending California's ban on the sale of violent videogames to minors before the Supreme Court. The law is being challenged by game makers and publishers.
Steven Spielberg and Kate Capshaw, Jeffrey and Marilyn Katzenberg and David Geffen are chairing the event, which is being organized by political consultant Andy Spahn. The DreamWorks trio hosted an event last November that raised $1 million.
Other recent contributions to Brown have come from Sally Field, who donated $5,000; Kirk and Anne Douglas, who each contributed $2,500; Michael Lombardo, $5,000; and Chris Albrecht, $5,000.
Although it doesn't match Brown in scope, Whitman has drawn her own share of industry donors, including Terry Semel, Michael Ovitz, Jerry Perenchio and Michael Lynton. On Tuesday, she donated another $20 million to her campaign, bringing the total amount of her own money she is spending on the race past $140 million.
But Brown has drawn on longtime ties to the business that extend to his first tenure as governor, a factor that helped him gain a fund-raising advantage when Gavin Newsom was still in the race for the Democratic nomination.
