School of Rock is a 2003 American comedy directed by Richard Linklater. When Dewey discovers that his students are musically talented, he secretly transforms the class into a rock band, teaching them the history and spirit of rock and roll while preparing them for a Battle of the Bands competition — all while concealing the scheme from the school's strict principal, played by Joan Cusack. Jack Black's performance was pure, unfiltered rock-and-roll enthusiasm, and his genuine musical ability — he could actually play guitar and sing — gave the comedy authenticity.

The child actors, many of whom were actual musicians, performed their own instruments on screen and in the film's soundtrack. Richard Linklater's direction was unusually structured for the famously improvisational filmmaker, but he gave Black freedom within scenes that resulted in some of the actor's most memorably manic moments. School of Rock earned $131 million worldwide on a $35 million budget.
