His library music appears in many productions of the 1950s and 60s, such as The Key Man (1957), Strange Awakening (1958) and Chris Marker's La jetée (1962).[2] Most infamously, his library piece "Grip of the Law" was chosen by Gordon Zahler as the opening titles of Ed Wood's Plan 9 from Outer Space.[3] More recently, he is credited with film-score music for the film The Piano Tuner of Earthquakes (2005) and was also writing a musical shortly before his death.
