My Scientology Movie, the newest film by the British documentarian Louis Theroux, vibrates with effort-with machinations and stunts and stitch ups that all seem intent on producing an "aha" moment that remains tantalizingly out of reach.

There's not a lot of shockingly new information per se, but watching Theroux filming covert Scientologists while they in turn film him, and so on, has its own sort of meta-charm.

New look at well-charted territory adds just enough to justify its existence.

The doc boasts no greater analysis into the churchs operations, though its irreverent comic stuntwork entertains.
