altPresident Obama has raised more than a half a million dollars so far this year from a handful of celebrity donors.

George Clooney, Steven Spielberg, Tom Hanks, Will Ferrell, Eddie Murphy, Kate Capshaw, Rita Wilson, and Dreamworks CEO Jeffrey Katzenberg have maxed out on their donations to the president this cycle at $69,100 each. That's a total of $552,800 from nine donors for Obama's war chest.

The money was raised in April when the president was on a West Coast fundraising swing, which included a couple of events in Los Angeles.

All nine members of Hollywood's A-list were at a small, exclusive fundraising dinner at the Tavern restaurant in Brentwood -- a wealthy Los Angeles neighborhood -- on April 22, according to the pool report.

The celebrities gave the maximum $2,500 individual contribution to Obama, a $35,800 donation to the Obama for Victory Fund and $30,800 to the Democratic National Committee (money that can be used to support Obama), according to filings with the Federal Election Commission.

And some of them have donated to other Democrats in need: Spielberg, Capshaw, and Hanks have each given $2,500 to Sen. Maria Cantwell (D-Wash.), who is up for reelection next year. Spielberg has also given $2,500 to Sen. Claire McCaskill (D-Mo.) who faces a tough 2012 fight. 

Katzenberg was listed as one of Obama's $500,000 plus bundlers in July and it's possible the Los Angeles event helped him earn that distinction. The CEO also gave $2 million in May to Priorities USA -- the independent expenditure committee formed by former Obama aides Bill Burton and Sean Sweeney.

Not all politically minded celebrities have given to Obama yet. ITK noticed actor Ben Affleck, who was a big John Kerry supporter in 2004 and has said he'd consider running for office one day, has yet to donate to the president. But there's still plenty of time for him to get on the action. After all, the election is still more than a year away.
