Acceptable Ethnic Targets: The gypsies are portraited as little more than bloodthirsty mercenaries. It is actually a better play on them than most of the public opinion about them in France in overall Europe.
Complete Monster: Jean-François de Morangias appears to be a foppish, crippled aristocrat, but is in reality a deadly enforcer for an evil cult. After returning from Africa, he brought with him a lion that he controls and keeps in a state of constant agony, using it to slaughter people while the poor creature is in so much pain it can't control itself. He also reveals a rather perverse lust towards his sister Marianne and later rapes her. While he is merely The Dragon to the Cult's leader, he comes off as the far more cruel, evil and deadly of the two and his mastery of the Beast indicates he might be the one really in charge.
Older Than They Think: The idea of a Indian doing kung fu might sound new, but the 1969's film The Undefeated, directed by Andrew V. Mclaglen and starring John Wayne, already featured an Indian character shooting flying kicks and such in a rather tongue-in-cheek brawl scene.
