Paul Green, founder of the Paul Green School of Rock Music, is the focus of this month's new release "Rock School," a nonfiction documentary about Green's Philadelphia-based rock music school. As reported by the New York Times and the Philadelphia Inquirer, Green, who started the after-school music program in 1998 in his own living room, owns 5 other schools and licenses 3 others. He hopes to have 50 to 100 Paul Green School of Rock schools nationwide - some company-owned and others as franchises - in the next two years. Green, who is still refining the franchise contract for those new schools, considered suing the filmmakers of the 2003 comedy "School of Rock" (starring Jack Black) for basing their movie on Green and his schools without permission. He never filed suit.
