Byzantium… Gemma Arterton with bite.
Gemma Arterton and Saoirse Ronan (the lass from the much under-rated Hanna) play mother and daughter vampires on the run in present day Earth, the twist being that vampires are a male-only club, with any women vamps hunted down and murdered. So Gems and Saoirse have been on the run for centuries. Think Highlander meets Interview with a Vampire.
