Eleanor (Saoirse Ronan) and Clara (Gemma Arterton) are two very different vampires. Clara is a stripper at a strip club. Eleanor selects her victims carefully and seems to care about them. We see her pick and old man near the end of his life and he readily accepts his fate. A man--a hunter--tracks down Clara and she tries to get away but he catches up with her. He wants to know where Eleanor is--and calls her an abomination. Clara decapitates him--and they now have to flee their apartment, which they set afire.
Soon, Clara meets a mortal schlub, who is rich and lonely. He agrees to give them shelter. About forty minutes into the movie the true nature of these two vampire women are revealed, via flashbacks, an it's surprising, not what I expected. There are some great visuals here for a vampire movie, particularly a waterfall of blood. BYZANTIUM is a better than average vampire flick.
