The Naked Brothers Band: The Movie is a 2005 musical comedy film written and directed by Polly Draper.
The film opens with Nat and Alex introducing themselves and their documentary to the viewers. This is followed by a performance of The Silver Boulders' latest song "Motor Mouth" at the Hammerstein Ballroom.
Nat and Alex explain how the band used to consist of only themselves and was called The Naked Brothers Band (due to being partly naked and being brothers). Their childhood friend Cole was a member of the band as well before he had to move to Connecticut. During Nat's second preschool year, the band was renamed The Silver Boulders, which included Nat's preschool friends David, Josh, and Thomas. The band was managed by Cooper, another of his friends. Nat had written many original songs for The Silver Boulders, such as "Motor Mouth" and "Crazy Car", eventually leading them to be signed to Who's the Man Records, owned by John B Williams. A music video for "Crazy Car" is shown afterwards.
Things were going well for the band until Thomas shared a song he'd written called "Boys Rule, Girls Drool". Cooper refused to have that song performed. Nat on the other hand, wrote a song about a girl he had feelings for: Josh's stepsister, Rosalina. Thomas and Josh made fun of him for it, causing a dispute. The band spent less time with each other and eventually, Thomas, Josh and David decided to form their own band, The Gold Boulders.
