Blonde Venus (1932)

In director Josef von Sternberg's melodrama:

• the memorable entrance sequence in a jazzy German nightclub (to the beat of an African drum) in which singer Helen opened the cabaret show by first appearing in a full-body gorilla suit as a chained ape, led into the audience by chorus girls (carrying shields and spears) adorned with war paint on their faces and wearing large black afro wigs

  "Did you ever happen to hear of voodoo? Hear it and you won't give a damn what you do Tom-tom's put me under a sort of voodoo And the whole night long I dont know the right from wrong
  Hot voodoo, black as mud Hot voodoo, in my blood That African tempo has made a slave Hot voodoo, dance of sin Hot voodoo, worse than gin I'd follow a cave man right into his cave..."
