What is that movie?

I remember it was a movie where there were two women and a man, these two women turned into snakes, and I remember they lived in houses on top of the water. I also know it was happening some kind of festival, but I don't know what it was. It was probably an Oriental film, but I'm not sure. It looked like it was an old movie (at least in my head it looked like it was a movie from 1900 or something like this). I know it was an Oriental film because the women wore Oriental festival props.
