Jamie Lee Curtis, Matt Bomer, Martin Sheen, Jane Lynch, George Takei and George Clooney are among the Hollywood stars set to appear in the Los Angeles premiere of the play 8.

8, which was written by Milk screenwriter Dustin Lance Black, is based on the trial over the constitutionality of California's gay marriage ban, Proposition 8.

The 13-day trial held last year in San Francisco resulted in federal Judge Vaughn Walker, now retired, declaring the ban unconstitutional. Proponents of Proposition 8 appealed the ruling, and gay and lesbian couples in California remain barred from marrying.

“This play will continue to show Americans – one by one – that prejudice and fear cannot stand up to truth and justice,” Chad Griffin, board president of AFER, the group formed specifically to support the legal challenge to the law, said in a statement. “Try as they might, the anti-gay marriage proponents of Proposition 8 cannot hide their discriminatory arguments from the American people.”

The Broadway premiere of the event raised over $1 million for the fight to win marriage equality.

Clooney and Sheen will play plaintiffs' lead co-counsel David Boies and Theodore B. Olson, respectively. Maggie Gallagher, co-founder and former chairman of the National Organization for Marriage (NOM) will be played by Glee co-star Lynch.

8 will be performed as a reading at the Wilshire Ebell Theater for one night only on March 3.
