Dustin Lance Black's Prop. 8 Play: Who's Who

Longtime equality activist, actor-direct Rob Reiner will play David Blankenhorn, president of the Institute for American Values, who was one of two witnesses called by the opponents of gay marriage. "If the world sees what happens in this trial, they'll realize that the other side simply had no case," Reiner tells AP. "They presented no evidence and the witnesses that they did present — the two that they did — made our case for us."
