LIBERATE US

 (New York) 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.
