The Post-Gazette reviews movies from a family perspective:

'RV'
Rated: PG.

Best for: School-age children and above.

What you should know: Robin Williams plays a workaholic husband and father who cancels the family's Hawaii getaway and rents an RV so everyone can spend time together and he can secretly do some work. Cheryl Hines is his wife, and Joanna "JoJo" Levesque and Josh Hutcherson are their children.

Language: A handful of mildly offensive words are used.

Sexual situations and nudity: None, other than some kissing and veiled references to the married couple trying to plot some bedroom time together. A joke is made about someone "hooking."

Violence/scary situations: The RV is involved in a series of accidents or near-accidents, and Williams is the focus of almost all of them. He battles raccoons, rides down a hillside while pressed against the outside windshield and chases another vehicle and climbs aboard while it's moving. While not violent, Williams also has gross mishaps with sewage, leaving him covered in excrement.

Alcohol and drug use: Not much. Hines fixes martinis and a scene is set in a bar.

'Stick It'
Rated: PG-13.

Best for: Tweens and above.

What you should know: From the writer of "Bring It On," this is about a once-promising gymnast (Missy Peregrym) who gets into trouble and is ordered to a gymnastics academy, where she encounters a hard-nosed coach, played by Jeff Bridges.

Language: Teens use some crude or offensive language.

Sexual situations and nudity: None, although teens flirt, and a mention is made of a married woman having an affair.

Violence/scary situations: A daredevil rides a bike at a construction site and crashes through a home's glass doors but isn't hurt. An adult and children fall off gym equipment, but no one is seriously injured.

Alcohol and drug use: Adults are shown drinking.

'Akeelah and the Bee'
Rated: PG.

Best for: School-age children and up.

What you should know: This is an inspiring, entertaining movie about an 11-year-old Los Angeles girl named Akeelah Anderson (Keke Palmer) who is catapulted into the world of spelling bees, longtime contestants and an erudite coach.

Language: A couple of mild words, the sort heard on TV, turn up.

Sexual situations and nudity: None.

Violence/scary situations: References are made to an adult and a child who died from an accident or illness.

Alcohol and drug use: None.

'United 93'
Rated: R.

Best for: Mature teens and older moviegoers who can handle the wrenching subject matter.

What you should know: This is the story of United Airlines Flight 93, how it was taken over by hijackers on 9/11 and how the passengers and crew fought back. The plane, headed for Washington, D.C., crashed near Shanksville, Somerset County, killing all aboard. Its R rating is for language and some intense sequences of terror and violence.

Language: The f-word and other profanities are used.

Sexual situations and nudity: None.

Violence/scary situations: We watch news footage of hijacked planes flying into the World Trade Center and see the towers on fire. The most disturbing scenes occur aboard the flight, where the hijackers kill crew members, take over the plane and threaten to blow it up and the passengers fight back. The saddest moments come as passengers and flight attendants call their family members to say goodbye.

Alcohol and drug use: None.
