Tina Fey, a performer and head writer for 'Saturday Night Live,' has deftly adapted Rosalind Wiseman's nonfiction dissection of teenage girl societal interaction, 'Queen Bees and Wannabes: Helping Your Daughter Survive Cliques, Gossip, Boyfriends and Other Realities of Adolescence.'

Though narrative cohesion isn't the strength of 'Mean Girls,' which works better from scene to scene than as a whole, the intelligence shines in its understanding of contradictions, keeping a comic distance from the emotional investment of teenagers that defined 'Ridgemont High' and later the adolescent angst movies of John Hughes.

The documentary 'Certifiably Jonathan' has engrossing moments in it. How can it not? It's got a great subject - the extraordinarily voluble comedian Jonathan Winters, whose constant rush of words can be like a blizzard: beautiful, maddening, exhausting, and finally beautiful again. But it's not a great film.

In period films, it always helps to have someone built to carry a sword, and Channing Tatum clearly hasn't missed a workout for the past two years, so he fits the bill in that regard.
