This is an animated, autumnal, buddy caper about time-traveling turkeys that are determined to change history and keep themselves and their kinfolk off the Pilgrims' menu on their first Thanksgiving in the New World.

When astute Reggie (voiced by Owen Wilson) tries to warn his free-range flock what's in store for them, they shun him as "anti-corn" yet, when they discover he's right, he's tossed out of the coop. Then he's rescued by the plucky daughter of the president of the United States, who designates Reggie as this year's "pardoned turkey."

While devouring delivery pizza and cable TV at Camp David, Reggie is kidnapped by renegade Jake (voiced by Woody Harrelson) and convinced that it's their destiny to use S.T.E.V.E, an egg-shaped, government-built time machine (voiced by "Star Trek" vet George Takei), for a Turkey Freedom Front trip back to the Plymouth Colony, November 1621.

Upon landing, the roosters confront gun-toting colonists, but they're saved from the Harvest Feast by Jenny (voiced by Amy Poehler), the sassy daughter of Wild Turkey Chief Broadbeak (voice by Keith David), leading to a daring raid on the settlers' weapons and the arrival of Chuck E. Cheese pizza.

Pixar animator-turned-director Jimmy Howard ("Horton Hears a Who!") devises admirable camera work in his fast-paced, meticulously choreographed action sequences. But the shallow script by Howard with producer Scott Mosier is stuffed with cranberry-sauced humor and gentle jabs against factory farming -- plus nods

to "Back to the Future" and "Bill & Ted's Excellent Adventure."

Problem is: it lacks the inherent cleverness and fun of similarly fowl-themed "Chicken Run." Nevertheless, the vocals are superb and composer Dominic Lewis skillfully uses electric guitar and pit bass, along with ethnic instrumentation.
