In the past, Morgan Freeman and John Lithgow have displayed their acting chops by playing God (Bruce Almighty) and a doctor from outer space (3rd Rock from the Sun). Now, they’re getting the chance to stretch a bit further by stepping into the characters of Boies, Schiller & Flexner chairman David Boies and Gibson, Dunn & Crutcher appellate star Theodore Olson.

Freeman and Lithgow have been tapped to play Boies and Olson, respectively, in a one-night staged reading of “8,” a new play by playwright and Oscar-winning screenwriter Dustin Lance Black about the legal fight over California’s controversial anti–gay marriage Proposition 8. The reading is scheduled for September 19 at the Eugene O’Neill Theatre in New York.
