Moore authored the stage musical Up on the Roof (later directing his own film adaptation in 1997) and wrote the BBC series Traffik (with Bill Paterson, Lindsay Duncan, and Julia Ormond). The series was later adapted as the Hollywood film Traffic. Moore went on to write and direct Under Suspicion (with Liam Neeson) and as writer only for The Quick and the Dead (with Sharon Stone).
