Russell Brand, Scientologist? Tom Cruise Not Interested (Video)

DOWN: Russell Brand

The Brand-hosted MTV Movie Awards tumbles 29 percent in total viewers, with 3.2 million watching the latest "Twilight" best "The Hunger Games" for movie of the year.

Whether or not he's spinning a yarn, Russell Brand -- whose off-the-cuff observations and lack of a filter make him the perfect late-night guest -- has a way of making you think he's telling the unvarnished truth.

The comic actor riffed on Tom Cruise and Scientology during his Tuesday night guest appearance on Conan, pronouncing to big laughs: "Firstly, he's a glorious man and he's very kind and sweet. That's what you say if you want to continue to work in the film industry."

STORY: How Scientology Seduced Tom Cruise

Brand, who starred opposite Hollywood's most famous Scientologist in 2012's Rock of Ages, said he was interested in learning more about the religion from Cruise on set. "So every so often I'd say things like, 'Oh, Tom, sometimes I'm a bit lost in life' ... 'Tom, I wish I had a way of thinking more positively about the future.' That man had no interest in getting me in Scientology at all."

Lamented Brand: "If there's a cult that don't want me, I want to know why!"

(A theory? Russell's mouth might be too big for David Miscavige to muzzle.)
