While all actors are expected to be versatile, Denis O'Hare is one another level. His chameleon-like ability to disappear into roles has landed him parts in a variety of film projects, as well as starring roles in both HBO's True Blood and Ryan Murphy's American Horror Story. The latter gives O'Hare the chance to step into a new character every season, while his vampire villain Russell Edgington was True Blood's most beloved villain. So which show is easier to be on? Denis O'Hare recently revealed that while AHS is a dream job, it doesn't have the same familial feel that True Blood did. Plus, the material is darker.
