Prominent filmmaker Lisa Ling will screen her new documentary, "God and Gays," in Culver City on Thursday evening.

The screening comes as the Exodus International "gay conversion" therapy group prepares to shut its doors after renouncing its views, and the U.S. Supreme Court prepares to issue rulings this week on two matters concerning gay marriage.

The private screening will be followed by a panel discussion with Ling, Rick Jacobs of CourageCampaign.org and California state Sens. Darrell Steinberg and Ted Lieu, both Democrats.

The film documents the change of heart of Alan Chambers, president of Exodus International, which started in Anaheim 37 years ago as a small ministry to help those struggling to reconcile their homosexuality with the Bible's teachings.

It grew into the leading practitioner of the controversial "gay cure" movement, with 260 ministries around North America.

The screening will begin at 7:30 p.m. at the Cary Grant Theatre at Sony Pictures, 10202 W. Washington Blvd.

Tickets are available online.
