The penguins are back in returning director George Miller's animated sequel, and though a good deal of the novelty has worn off, the result still can be enjoyed by family audiences.
Now a dad, Mumble (voiced again by Elijah Wood) balances family concerns with coming to the rescue of his species when an atmospheric threat presents itself. Robin Williams returns to the voice cast, with Brad Pitt, Matt Damon and Sofia Vergara ("Modern Family") among the notable additions. DVD extras: three "making-of" documentaries; "Sing-a-Longs." *** (PG: AS) (Also on Blu-ray and Movies on Demand)
