Oscar winners Morgan Freeman and Marisa Tomei are heading for the Broadway stage for one night only, as part of a fundraising play about California's overturned same-sex marriage law.
Fellow actors Cheyenne Jackson, Anthony Edwards and Yeardley Smith will also be among the cast members of Milk screenwriter Dustin Lance Black's play, 8, read through.
The production focuses on the legal efforts by officials at the American Foundation for Equal Rights to overturn the controversial Proposition 8 bill, which outlawed gay unions in the state, just months after its legalisation in 2008.
The play will be directed by Joe Mantello and take place at the Eugene O'Neill Theater on 19 September (11), according to trade paper Variety.
