Quadrophenia is a 1979 British film, loosely based on the 1973 rock opera of the same name by The Who. The film stars Phil Daniels as Jimmy, a young 1960s London-based Mod who escapes from his dead-end job as a mailroom boy by dancing, partying, taking amphetamines, riding his scooter and brawling with the motorcycle-riding Rockers.
