Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
In one of his early martial arts comedies, Jackie Chan's character 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. We see the snake retreat, then there's a 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 dead on the floor. The fight is a martial arts lesson for Chan's character. He holds up the cat's paw and concludes that he should combine a cat's claws with the style of martial arts he has been studying, called "Snake's Fist."
I've seen video of fights between cats and snakes on YouTube, but they were real fights, but this fight was set up just for the movie. It's cruel to treat animals this way just for our entertainment.
