While details on the pilot are scarce, Horror reportedly revolves around a sensitive therapist, Ben Harmon, and his gorgeous wife Vivian (Britton). O'Hare, who portrayed the villainous vampire Russell Edgington on True Blood last season, will play Larry, also known as Larry the burn guy (whatever that means).
American Horror Story is the brainchild of Ryan Murphy and Brad Falchuk, co-creator-executive producers of Fox's Glee and previously FX's Nip/Tuck. Murphy will direct the pilot, which begins shooting in April. Glee's Dante Di Loreto will also executive produce.
