Rated: PG.

Best for: Preschoolers who can sit attentively through a movie that's roughly an hour and a half (and all the previews and commercials before).

What you should know: This is the third movie in the series and the first in 3-D, where available. In addition to revisiting the Ice Age, it introduces a land of dinosaurs below with a new cast of characters and voices.

Language: None.

Sexual situations and nudity: Nothing notable, other than some animal flirtation, labor pains and discreet birth of a woolly mammoth.

Violence/scary situations: Cartoon falls, chases and captures, ferocious dinosaurs, animal skeletons and a story about a weasel who lost an eye to a dinosaur and now wears a leafy eye patch but it's all pretty mild.

Alcohol and drug use: None.

Rated: PG-13.

Best for: Mature high school students and older.

What you should know: This is light Woody Allen about a crotchety genius (Larry David) who improbably opens his New York apartment to a Southern runaway (Evan Rachel Wood) and, even harder to believe, marries her. When her divorced parents come looking for her, their lives are turned upside down too.

Language: Periodic discussions are adult, more than the language which does include brief profanity.

Sexual situations and nudity: A woman shares her bed with two men and exhibits oversize nude photos, and a man realizes late in life that he is attracted to other men. Kisses are exchanged between couples.

Violence/scary situations: Unsuccessful suicide attempts, played for laughs.

Alcohol and drug use: Adults drink wine, beer or shots and sometimes get tipsy, and there is a quickie scene with a bong.
