Actor Mark Ruffalo and director-writer Lisa Cholodenko are cheering the four Oscar nominations for the lesbian moms flick The Kids Are All Right.

The film has been nominated for best picture and one of its leading ladies, Annette Bening, received a best actress nomination for her portrayal of a lesbian mother trying to hold her family together.

Ruffalo received a best supporting actor nom for his portrayal of biological father Paul. The film's writers, Cholodenko and Stuart Blumberg, have also been nominated for best screenplay.

In a statement released on Tuesday, Ruffalo called his nomination a win for marriage equality.

“It is with great honor and humility that I receive my Oscar nomination,” Ruffalo said. “The kind of acting that happened in this movie does not exist in a bubble. Any honor that I receive must be shared with Julianne Moore, Annette Bening, Josh Hutcherson, Mia Wasikowska, the rest of the cast, and of course the inimitable Lisa Cholodenko.”

“This nomination is a win for Marriage Equality and that is the most I could hope for,” he added.

In her statement, Cholodenko also thanked the cast of the film, then added that she regretted Julianne Moore not being nominated.

“But the Picture nomination is as much hers as ours,” Cholodenko said. “We couldn't have made this film without her heart, smarts and loyalty, not to mention her outstanding performance.”

Ruffalo 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.
