Kate Churchill, formerly part of the Lookinglass Theatre, a believer in yoga, challenges 29-year-old journalist Nick Rosen to investigate the worldwide yoga industry in “Enlighten Up!”, a documentary likely to satisfy those whose ears perk up and legs cross tightly at the thought of such a journey. It’s a worldwide road trip that includes a wide range of practitioners and engages a number of controversies surrounding permutations of the practice. Churchill’s own presence in the documentary is less ingratiating that that of neophyte Nick, but there are genial diversions throughout the travelogue. 82m. (Ray Pride)
