Dewey Finn is a down-on-his-luck, energetic, 30-year old, wannabe rock superstar who at the very start of the film is kicked out of his own band 'No Vacancy' due to his antics such as constant 20 minute solos and stage diving.

Role in the movie Edit

Sometime before the events of the movie he helped form the band 'No Vacancy' where he was a guitar player, but due to his constant 20 minute guitar solos and stage diving one of which rendered him unconscious, he was kicked out


Dewey is unemployed but is forced to try and find a job after Ned and his girlfriend,Patty, threaten to kick him out of their apartment due to Dewey not paying his share of the rent. In the film Dewey gets a job as a substitute teacher for Horace Green Prep School by pretending to be his friend Ned Schneebly.

When walking past the class' music class in his spare time, he discovers the students are musically talented and decides to make them into a rock band and compete in the Battle of the Bands and get revenge on his old band. He manages to get the class to go along with the idea by telling them that it is a school project and if they keep it secret from the other staff, they can start before the others. Dewey and the class manage to keep their band practices secret from the rest of the school by blacking out windows, sound-proofing the classroom and placing cameras to watch the hallways. He is eventually exposed as a fake and mistaken to be a pervert at Parent's Night at the school after Ned is forced by Patty to call the cops, but he runs away and the next day he is convinced to go with the kids and play at the Battle of the Bands but they lose the cash prize to his old band No Vacancy, but the crowd loves them more and calls for them to come back on stage while booing No Vacancy. Later, he forms his own after school program for the kids and thanks to Battle of the Bands they have a lot of potential gigs and record offers that Summer made the deals on her cell phone

Personality Edit

Dewey starts the movie as a self-centered, egotistical, energetic rocker who was not very intelligent in areas other than rock. By the end of the movie he becomes much kinder, more likable, and becomes a great music teacher.
