Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
Inside a large Native American building near Jamestown Virginia during the early 17th century, John Smith throws gunpowder into a fire to impress the savages. During the commotion we see a brief shot of an Indian painted black wearing a thin green snake over his ear. It's most likely a Rough Green Snake. Unfortunately, the style didn't catch on with the colonists. But, hundreds of years later, according to Ken Burns' documentary on the Roosevelts, Alice, one of Theodore Roosevelt's daughters, wore a wriggling green snake as jewelry. That I need to see. According to Wickipedia, the snake was her pet named Emily Spinach, because it was green. Probably a rough green snake or smooth green snake.
