"Fame" moves from the concrete canyons of Manhattan to the woodsy splendor of the Catskills in this exhilarating musical about a summer-theater camp for young performers. Daniel Letterle and Joanna Chilcoat star. This is the directorial debut of Todd Graff, who wrote the screenplay and is an alum of the performing-arts camp Stagedoor Manor, where the film was shot. Stephen Sondheim has a cameo.
