The play, directed by Rob Reiner, will debut at the Wilshire Ebell Theatre on Saturday, March 3, for an exclusive fundraiser to support marriage equality efforts across the country.

Other cast members include Matt Bomer, Campbell Brown, Jesse Tyler Ferguson, Cleve Jones, Christine Lahti, Matthew Morrison, Rory O'Malley, Yeardley Smith and George Takei.

The story for 8 is based on the trial’s closing arguments in June 2010.  Some of the scenes also include flashbacks to other trial testimony, including a statement by the Prop. 8 supporters’ star witness, David Blankenhorn, who told the court  “we would be more American on the day we permitted same-sex marriage than we were on the day before.”
