Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
Despite the name of the film, which means green cobra, there are no cobras in the movie, nor are there even any green snakes, but there is a python.
I don't know who is more insane - Klaus Kinski, the actor who played Aguirre and Fitzcarraldo and Cobra Verde, or Werner Herzog who made all of those great films. In this one, Klaus Kinski plays Francisco Manoel da Silva aka Cobra Verde, a Brazilian bandit, who is hired by a plantation owner to manage his hundreds of slaves. But when the owner finds that Kinski is a notorious bandit who impregnated all three of his daughters, he and the other rich men of the region cook up a plan to send Cobra to Africa to buy more slaves, thinking he will surely die because the insane king of Dahomey has vowed to end the slave trade and kill any whites who come to his country. Cobra ends up re-starting the slave trade, but after the king tries to kill him, he helps the king's brother take the throne by training an army of women warriors - hundreds of which we see training to fight. (Much of the film was shot in West Africa using hundreds or maybe as many as a thousand extras.) When Cobra and the women are advancing on the king's residence, we see one of the king's men dancing with a small python, which I think is a ball python, native to West Africa. Then he puts the snake on the ground and dances around it. Cobra's advisor tells him it's the sacred python from the king's temple and that they must turn back because nobody gets past the python alive, but Cobra doesn't believe in such witchcraft. He tells them he was a snake in his own country and then kicks the snake aside and calls for the women to attack. I'll bet the scene is more powerful if you think that the snake is deadly, not the kind you can buy at PetCo.
