The scene at the Voodoo club - which is choreographed and features Boscoe Holder, is almost identical to a scene in the James Bond film, Live and Let Die (1973), which - not only features Boscoe Holder's brother, Geoffrey Holder, but, is choreographed by him, as well.
Boscoe Holder, who was both choreographer and a dancer at Le Caldera (the voodoo club Drake goes to) is Geoffrey Holder's brother.
Actors, Wanda Ventham and Harry Baird, were also regular cast members of the TV show UFO.
