Isabelle McNally (House of Cards) is set to join Bates Motel in a recurring role for Season 5.
McNally will play Madeleine Loomis who is described as a warm and kindhearted woman, she also bears a striking resemblance to a young Norma Bates.
Carlton Cuse had this to say about the season which can also be said to offer insight:
“We wanted the final season to allow us to do our [spin] of the Psycho lore. We will be colliding with certain events in the narrative of the film, but it would be boring to just recreate Psycho.”
In the film Loomis was the last name of Sam Loomis the boyfriend of Marion Crane. The fifth and final season of Bates Motel will be released next year.
