Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
You can watch this sort of thing on YouTube every day now, but back in 1978 this must have been as shocking as it was horrible to treat animals this way for our entertainment. In one of his early martial arts comedies, Jackie Chan finds his pet cat fighting a cobra and cheers him on until the snake is dead. (A cat really fights a cobra here, but we don't know the true outcome. The snake retreats, then they cut to a shot of a dead snake next to the cat. We don't know if the cat killed the snake or if it's a different snake.) Chan holds up the cat's paw and concludes that he should try to combine a cat's claws with "Snake's Fist" the style of martial arts he has been studying.
