'Mamma Mia!'

Rated: PG-13.

Suitable for: Tweens and older.

What you should know: Filled with jubilant ABBA songs, this is an adaptation of the play about a young bride-to-be (Amanda Seyfried) who invites three strangers to her wedding, hoping to figure out which is her daddy. Meryl Streep is her single mother who runs a hotel on a Greek island, and Pierce Brosnan, Colin Firth and Stellan Skarsgard are her long-ago loves.

Language: Nothing notable.

Sexual situations and nudity: A man's naked behind is shown, there is much flirtation and sexually charged and alcohol-fueled dancing. Streep's character obviously slept with each of the three men one memorable summer. A joke is made about someone being "knocked up," and Streep comically revs a drill while discussing her celibacy.

Violence/scary situations: None.

Drug or alcohol use: Lots of champagne and other alcohol is consumed.

'The Dark Knight'

Rated: PG-13.

Suitable for: Children roughly 9 or 10 years old and up.

What you should know: This is the second Batman movie with Christian Bale. It features Heath Ledger, who died in January of an accidental overdose, as The Joker and is a dark movie that could be too long (2 1/2 hours), intense and scary for younger, sensitive moviegoers.

Language: A harsher version of darn and a couple of cruder words for backside.

Sexual situations and nudity: A few kisses are exchanged.

Violence/scary situations: This is where the movie earns its rating, with people shot, injured or killed in fiery explosions, poisoned, beaten and, in one case, disfigured. A woman and her two children are kidnapped and a gun is held to her head and to her son's. Although The Joker's makeup and stories about how his face was scarred are unsettling, it's Harvey Two-Face who may be the most disturbing. Part of his cheek and lips have been burned or gouged away, one of his eyes pops and his skin bears the marks of fire damage.

Drug or alcohol use: Adults briefly are shown with champagne and other alcoholic beverages.
