Brad Pitt cut a check to the Human Rights Campaign in support of same-sex marriage, and he wants you to do the same.

The national organization, which is working in support of marriage equality across the country, announced the movie star's pledge today asking supporters to match his generosity in the next 24 hours.

$25,000 of his gift will go toward the fight to pass Washington's Referendum 74, which would uphold the legislature's legalization of same-sex marriage. The rest will go toward efforts in Maine, Maryland and Minnesota.

"This is our last chance to make a difference," Pitt says in a statement on the Campaign's website. "If you're like me, you don't want to have to ask yourself on the day after the election, what else could I have done."

According to Washington's Public Disclosure Commission, the Human Rights Campaign National Marriage Fund has raised about $517,000 so far. Washington United for Marriage, the pro-R74 camp, has seen plenty of other high-profile support, including $2.5 million from Amazon CEO Jeff Bezos and $600,000 from Bill and Melinda Gates. With that kind of backing, it's no surprise the campaign is out-fundraising Preserve Marriage Washington by about $9 million.
