The Naked Brothers Band is a (fake) documentary glamorizing the life of two kid rock stars. It's supposed to be a kids' movie, but it contains a surprising amount of sexual content and other iffy behavior for one. 6-year-old Alex "dates" his 20-year-old babysitter. He also states that he would like to "squeeze boobies" two times, and gives a Chinese version of the middle finger to a fellow band member. Nat says "crap" and there is a slightly offensive joke about Jesus ("He's the best President we've ever had!"). As product placement goes: Cheerios, Game Boys, and what appears to be Sierra Mist.
Nat and Alex Wolff are the two founding members of the most popular band around: The Silver Boulders. The band members are the best of friends. The only thing that could break them apart is a feud over which song they should play at their next concert: "I'm the God of Rock and Roll", "Boys Rule, Girls Drool", or "Rosalina". Since Nat is the leader of the group, he says that they go with his song, "Rosalina". But the others don't like how bossy he's becoming, and they quit to form their own band, leaving Nat and Alex with the Silver Boulders.
The two hire their old friend who returned from filming his Cheerio's commercial, and Nat's crush, Rosalina, to start a new band with them: The Naked Brothers Band.
While it's (for the most part) kid-friendly, the acting and music is absolutely horrible. Better-acted and sung, more kid-friendly movies that glamorize the life of a star are The Lizzie McGuire Movie and Hannah Montana.
