Here's How Patton Oswalt Knew That Leah Remini Would Leave The Church of Scientology

Patton Oswalt stopped by Watch What Happens Live With Andy Cohen on February 28 to chat all things A.P. Bio. But, the talk veered more toward celebrity dish than cellular processes.

Callers questioned the comedian about a range of topics, including who his favorite co-star has been. "It's Charlize Theron," he answered. "I got to do scenes with this actor that's working on this [high] level, [so] you know that you're going to be doing your best work because you're with someone that makes you up your game."

Though he admired Theron's acting skills, Oswalt did have one concern, however: her height. "She's very, very tall," he said, laughing. "The amount of phone books doesn't exist anymore to get me on her level. I care about the rainforest." 

The last caller of the night asked Oswalt about another co-star. "I want to know if there was any hint of Scientology on The King of Queens set with Leah Remini," she said. Oswalt laughed at the question, then offered a straight-shooting response.

Watch the clip above to find out if, indeed, Oswalt could sense the actress' devotion to L. Ron Hubbard — and why he thought she would eventually leave the church. Hint: the answer involves Remini hiking through the woods.
