Actor Mark Ruffalo, who stars in the lesbian moms movie The Kids Are All Right, and his wife Sunrise have recorded a video urging New Yorkers to support the legalization of gay marriage.

“We're raising our three kids to treat everyone with dignity and respect,” Sunrise says in the 31-second video.

“We believe everyone should have the right and the chance to be with the person they love, straight or gay,” Mark adds. (The video is embedded in the right panel of this page.)

The Ruffalos' ad is part of an ongoing campaign that features prominent celebrities and politicians. The campaign, backed by the Human Rights Campaign (HRC), the nation's largest gay advocate, has previously featured singer-songwriter Moby, actresses Fran Drescher and Julianne Moore, fashion designer Kenneth Cole, Jeanne Moutoussamy-Ashe, the widow of tennis great Arthur Ashe, and New York City Mayor Michael Bloomberg.

The campaign created a stir when it recruited Barbara Bush, the daughter of former president George W. Bush, to record a video.

Mark Ruffalo, who received an Oscar best supporting actor nomination for his portrayal of biological father Paul in The Kids Are All Right, is expected to team up with Glee creator Ryan Murphy in the upcoming big screen adaptation of the Larry Kramer AIDS drama The Normal Heart.
