Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
In a beautiful film by the great French director Jean Renoir, a young English boy living in India sees a snake charmer and develops a fascination with cobras. He sees one in the bushes at a small shrine next to a large banyan tree where people leave milk as an offering to a god. He returns with a bowl of milk for the snake and plays a flute to try to lure it out. (Based on the misconceptions that snakes like milk, and that cobras are attracted to music.) The snake comes out and hoods up. Later we see his dead body, apparently after being bitten by the cobra. The cobra use here looks like a real one, but I'm not sure what species it is.
