According to Deadline Hollywood veteran Irish theater actress and director Fiona Shaw (pictured right), who is probably best known in the U.S. for her role as Aunt Petunia in the Harry Potter movies.
On “True Blood” she will play Marnie, a mousy, timid and secretly self-loathing storefront medium and palm reader who is taken over by the spirit of a powerful witch. The character was originally envisioned younger but is being adjusted for Shaw.
Look for more on “True Blood” Season 4 as it comes.
