George Clooney will participate in a benefit one-night-only reading of Dustin Lance Black’s 8, a play chronicling the historic legal challenge to California’s Proposition 8, the American Foundation for Equal Rights announced today. Rob Reiner, an AFER founding board member, will direct the performance, which will take place at the Wilshire Ebell Theatre on March 3.

Black based the play on actual court documents and his interviews with the plaintiffs from the case to overturn Proposition 8, which denied gay and lesbian Californians their rights to marry. Clooney is the first of what is expected to be an all-star cast similar to the one that premiered the play in New York last September. “It is astonishing that gay and lesbian Americans are still treated as second-class citizens,” Clooney said in a statement. “I am confident that, very soon, the laws of this nation will reflect the basic truth that gay and lesbian people — like all human beings — are born equal in dignity and rights.”
