Godfrey Ho used American actor Richard Harrison extensively as the lead role in many of his films. Harrison, a European B movie star in the 1960s and 1970s, agreed to act in several of Ho's films in the early 1980s, although this footage was later spliced into many more of Ho's productions without his prior agreement; the damage done to his acting career by this association with Ho's films led Harrison to retire in 1990. Ho's filmmaking also included uncredited and apparently unauthorised use of music from "Miami Vice", "Fight! Iczer One", "Kamen Rider Super-1", "Star Trek", "Star Wars", the Super Sentai franchise, "Combat Mecha Xabungle", Kyojuu Tokusou Juspion, and Silent Running, and composed by Wendy Carlos, Vangelis, Pink Floyd, Tangerine Dream, Clan of Xymox, Hideki Matsutake, Steve Hillage, and Peter Schickele among others, as background score in his movies. The song "Just Like You" by Chris & Cosey was used without permission twice in the film "Deadly Silver Ninja" (1978).
