Brad Pitt currently stars in the number-one movie in the country, Burn After Reading.

He also appears to have found a new, number-one cause to focus on.

The actor donated $100,000 to fight California's Proposition 8, a ballot initiative that would take away same-sex couples' right to marry.

"Because no one has the right to deny another their life, even though they disagree with it, because everyone has the right to live the life they so desire if it doesn't harm another and because discrimination has no place in America, my vote will be for equality and against Proposition 8," Pitt said in a statement.

No matter where you stand on gay marriage - and we're curious to hear reader thoughts on the topic - it's hard not to admire Pitt for taking a stand on such a controversial issue.
