The Gist: After being bitten by a snake a woman transforms into a blood sucking vampire.
Clarification: I had to go to the IMDB plot summery for that. This is a very artsy film full of camera tricks, screen filters and nothing plot wise is actually spelled out. Basically a woman is doing a video diary the whole movie explaining what's going on with her which is followed by scenes of her doing stuff with no dialogue or explanation till her next days diary and even then it's not very clear what's happening. Basically an over thought out music video or late 90's playboy strip tease video would be the best comparison I can make.
Selling Point: Generally the "Doing stuff" portion is either in lingerie, sexy club wear or nothing at all.
Female Vampire Factor: Your vampire in this film is played by British actress Melanie Denholme
Speaking of the feeding, she does have fangs but as seen on the box art they are the piranha style and not your traditional vampire fangs.
