NEW YORK (AP) — Anthony Edwards, Morgan Freeman, Cheyenne Jackson, Christine Lahti, Rob Reiner, Yeardley Smith and Marisa Tomei will appear in a one-night-only reading on Broadway of a play about Proposition 8.

On Wednesday, producers announced some of the cast members who will perform in Dustin Lance Black’s play “8’’ as part of a fundraiser at the Eugene O’Neill Theatre on Sept. 19.

Proposition 8 is the measure approved by California voters in 2008 that bans gay marriage in the state. A federal judge struck down the law last year. That ruling is being appealed.

The play, which is based on the trial transcript and interviews, will be directed by Tony Award-winning actor and director Joe Mantello.

Black won the Oscar for “Milk,” his biopic of gay-rights pioneer Harvey Milk.
