I don't know how many people have seen this, but YouTube added the full play to view for free. It's pretty awesome and very accurate.

"8": A Play about the Fight for Marriage Equality - YouTube

Synopsis: Featuring an all-star cast including George Clooney, Brad Pitt, Martin Sheen, Jamie Lee Curtis, Jane Lynch, Kevin Bacon and others, "8" is a play written by Academy Award winning screenwriter Dustin Lance Black and directed by acclaimed actor and director Rob Reiner. It is a powerful account of the case filed by the American Foundation for Equal Rights (AFER) in the U.S. District Court in 2010 to overturn Proposition 8, a constitutional amendment that eliminated the rights of same-sex couples to marry in the state of California. Framed around the trial's historic closing arguments in June 2010, 8 provides an intimate look what unfolded when the issue of same-sex marriage was on trial.
