Jack Black goes back to School! A sequel to Jack Black’s ‘School of Rock’ is in the works. Black is attached to reprise his role as rock star wannabe/substitute teacher Dewey Finn, who in the original film turned a class of fifth-grade high-achievers into high-voltage rock ‘n’ rollers. Richard Linklater is attached to direct again, with Scott Rudin returning as producer. Mike White, who penned the 2003 comedy, is writing the screenplay, titled ‘School of Rock 2: America Rocks,’ which picks up with Finn leading a group of summer school students on a cross-country field trip that delves into the history of rock ‘n’ roll and explores the roots of blues, rap, country and other genres. The original film was a box office hit – costing just $30 million to make and earning $131 million worldwide. Black, who recently dropped out of the Todd Phillips-helmed comedy ‘Man-Witch,’ stars in two upcoming high-profile comedies: Ben Stiller’s ‘Tropic Thunder,’ opening Sep. 19, and the Judd Apatow-produced “Year One,” which is expected next summer.
