IF YOU WANT to see one of the world's most incredible inventions, a transport device known as the Forevertron, you'll have to see Mana: Beyond Belief. The Forevertron's mysterious and fantastic existence is revealed at the end of Peter Friedman and Roger Manley's beautifully shot international exploration of "mana" – explained as "an object that produces something that makes you feel there's some power there." Without intrusive narration or interstitials explaining specific locations (not that they're needed), the travelogue is occasionally solemn (pausing amid worshippers gathered around a golden boulder in Burma, lingering with crowds at the Shroud of Turin), though power finds a lighter touch amid Japanese cherry blossoms, Elvis fans at Graceland, low-rider drivers cruising New Mexico, and a perfectly detailed paper car that's ceremoniously burned at a funeral in China. There's a fascinating segment about when power fades – as when a prized Rembrandt painting loses its glow after its authorship is questioned – and some weird turns; for the right price, you too can buy the shriveled body part said to be the hand of Edgar Allan Poe. While Mana does compare in some ways to other New Agey, these-are-the-docs-of-our-lives (Baraka, etc.), it also has a sharp sense of humor: If you don't bust up during the scene that reveals the real dirt on those flags that fly over the US capitol, your name is George W. Bush. See Rep Clock for Roxie show times. (Cheryl Eddy)
