Set in 1959, this fun computer-animated effort follows Surly (voiced by Will Arnett), a greedy, self-centered squirrel who is exiled from his home in the park after he accidentally destroys his community's winter food stores. Banished to the mean city streets, Surly hatches a plan to rob an upscale nut store and restock the park's larders. Brendan Fraser, Katherine Heigl, Stephen Lang, Maya Rudolph, and Liam Neeson also provide voices. 86 min. Widescreen (Enhanced); Soundtrack: English Dolby Digital 5.1; Subtitles: English (SDH), Spanish, French; bonus shorts.
