Release date: Dec. 4Distrib: Paramount After a commanding liftoff at the Toronto Intl. Film Festival, Jason Reitman’s sophisticated romantic dramedy “Up in the Air” is well positioned to land significant kudos. The film has already received broad critical support — Rotten Tomatoes’ postfestival survey gave the pic a perfect 100% rating. Much of the buzz circulated around Reitman’s command of the material, as both writer and director, and strong perfs from Oscar winner George Clooney, honestly exploring what many see as the actor’s own personal issues, and supporting ladies Vera Farmiga and Anna Kendrick (recipient of the Palm Springs Rising Star Award at the festival in January). Reitman is no outsider, having won much praise for his 2007 sleeper hit “Juno,” which received four noms, including a win for Diablo Cody’s original screenplay. But “Up in the Air,” with both its likable cast of characters and timely look at unemployment, has the right mix of comedy and social commentary to fly even higher on Oscar night.
