A documentary about the 108 Productions’ run of Terrence McNally’s play Corpus Christi will premiere on April 29.

An online petition by the right-wing Catholic site America Needs Fatima has drawn over 7,000 signatures to date calling on the Castro Theater in San Francisco to cancel the engagement. It calls Corpus Christi: Playing with Redemption blasphemy.

In 2010, a student at Tartleton State University in Stephenville, Texas, planned to present a scene from the play as the final for his master’s level stage directing class. The presentation would not have been open to the public. However, an uproar about the presentation ended with its cancellation after pressure from the offices of Gov. Rick Perry and Lt. Gov. David Dewhurst, who is now running for U.S. Senate.

That summer, 108 Productions brought the play to Cathedral of Hope in Dallas.

The play portrays Jesus as a gay man in Texas in the 1950s.

The opening of the movie will launch the I AM Love Campaign, whose mission is to change the story on religious bullying and homophobia, in all ages and walks of life, by first learning to love the self.
