Whilst Chow is credited with producing many films, in the audio commentary for the UK release of "Zu Warriors from the Magic Mountain", Tsui Hark was asked the elementary question of Chow's role as a film producer, explained that this credit is mostly meaningless. Tsui stated that any producer's role at the studio was often nothing more than to greenlight and ensure funding of the project, and that producers such as Chow would rarely, if ever, set foot on the set during the making of the film. Raymond Chow officially announced his retirement in Hong Kong on November 5, 2007.
