Manny (voiced by Ray Romano), Sid (John Leguizamo), Diego (Denis Leary) and Ellie (Queen Latifah) return for the third film in the computer-animated Ice Age series, in 3D at some theaters. Obsessed acorn hunter Scrat also returns, and he gets distracted by a comely female squirrel-rat. The Scrat parts are funny. The rest of the film is routine family fare. Nothing awful, but a bit stale. 93 minutes.
