Brad Pitt Joins 'Prop 8' Play, Won't Marry Angelina Jolie Until Everyone Can Wed Freely

Brad Pitt has joined a star-studded cast in the play 8 that will premiere in L.A on Saturday in an aim to advocate for gay-marriage rights.

Pitt will be joining George Clooney and Dustin Lance Black, in a one-night reading of the play that will be performed at the Wilshire Ebell Theatre on Saturday.

The Oscar-nominated actor will play the part of U.S. District Chief Judge, Vaughn R. Walker, who overturned California's gay-marriage ban in 2010, after ruling that Proposition 8 was unconstitutional.

Martin Sheen, David Boies, Jamie lee Curtis, Matthew Morrison and Matt Bomer will also star in the play, which will raise funds for promoting gay-marriage rights.

The American Foundation of Equal Rights and Broadway has announced that the play will be live-streamed on YouTube at 7:45 p.m. on Saturday. A pre-show will also be live-streamed with an introduction from Director Rob Reiner, who will give context about the play and issues being addressed.

At long last each and every American will be able to see for themselves what happens when prejudice and fear are put on trial in a court of law, said AFER board president Chad Griffin in a statement, CNN Reported.

For over two years, the anti-marriage proponents of Proposition 8 have fought tooth and nail to hide their discriminatory arguments from the American people. But on Saturday night, thanks to YouTube and our incredible cast, people across the nation, from Los Angeles to Little Rock to Baltimore, will get to watch as our Constitution's promise of liberty and equality for all is protected.

Kevin Bacon, Jane Lynch, John C. Reilly, Campbell Brown, Chris Colfer, Jesse Tyler Ferguson, Cleve Jones, Rory O'Malley, George Takei, Yeardley Smith, Vanessa Garcia, Jansen Panatierre, James Pickens, Jr., and Bridger Zadina will also star in the play that first premiered on Broadway in September.
