Julianne Moore and Zach Galifianakis have joined the cast of gay rights drama Freeheld.
Ellen Page is already on board to star as New Jersey car mechanic Stacie Andree, who battled along with her police detective girlfriend Laurel Hester, to try and secure Laurel's pension benefits after the policewoman was diagnosed with a terminal illness.
Now The Hollywood Reporter has revealed Julianne will play Laurel, in Peter Sollett's film based on the 2007 Oscar-winning documentary short of the same name.
As they were in a lesbian relationship and not married in the eyes of the law, Stacie was not entitled to a widow's pension after her girlfriend's death.
Ron Nyswaner - Oscar-nominated for Philadelphia, which starred Tom Hanks and Denzel Washington - has written the screenplay based on Cynthia Wade's award-winning documentary, Freeheld. Wade's film won the Oscar for best short documentary in 2008.
Zach will play Garden State Equality activist Steven Goldstein.
Filming is expected to begin in the summer.
