School of Rock is a 2003 American comedy film directed by Richard Linklater, written by Mike White, and starring Jack Black. The main plot follows struggling rock singer and guitarist, Dewey Finn (Black), who is kicked out of his band and subsequently disguises himself as a substitute teacher at a prestigious prep school. After witnessing the musical talent in his students, Dewey forms a band of fourth-graders to attempt to win the upcoming Battle of the Bands and pay off his rent. The picture's supporting cast includes White, Joan Cusack, Sarah Silverman and Miranda Cosgrove. School of Rock went on to gross over $131 million worldwide and became the highest grossing musical comedy of all time, until it was overtaken in 2015 by Pitch Perfect 2. A stage musical adaptation opened on Broadway in December 2015, and a television adaptation for Nickelodeon is also due to premiere in 2016. Wikipedia
