Gillian Anderson will be a series regular for season 3 of Hannibal.

The former X Files star plays Dr. Bedelia Du Maurier in the NBC psychological thriller, and Hannibal's psychiatrist will have an extended role to play when the series returns in 2015.

"The cast and crew of Hannibal are positively giddy to be welcoming Gillian to Season 3 as a series regular," said series creator Bryan Fuller, according to TVLine. "A striking presence on stage and screen, she brings wit, grace and intelligence to every role she embodies. Screenwriting is so much easier when you're inspired by a great actor and Gillian has filled the Hannibal writers room with wonderful inspiration. I can't wait for audiences to see her make a bigger meal out of the Cannibal than ever before."

Bedelia was last seen in "Mizumono," hoping a plan to Europe with the fugitive cannibal. When Hannibal picks up one year later, Du Maurier will still be by Hanni's side as he stalks a new victim.
