Irish actress Fiona Shaw has been cast as the new character “Marnie”, reportsDeadline. Fiona Shaw is probably best known in the U.S. for her role as Aunt Petunia in the Harry Potter movies.
Marnie is 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. Shaw is currently onstage at Dublin’s Abbey Theatre in a limited engagement of Henrik Ibsen’s John Gabriel Borkman opposite Alan Rickman and Lindsay Duncan. On U.S. television, she previosly co-starred on ABC’s limited seriesEmpire.
