At the Television Critics’ Association press tour, Showtime shared that macabre melodrama Penny Dreadful is returning May 1.

Eva Green, Timothy Dalton and Josh Hartnett—as pansexual werewolf Ethan Chandler—return to the series, as does Patti LuPone, who played the Cut-Wife woman in Season 2.

In the new season, she will play Dr. Seward, an American therapist who treats Vanessa's psycho-spiritual affliction.

Also joining the cast are out actor Sam Barnett (Jupiter Ascending) as Seward's young secretary; Shazad Latif as Dr. Henry Jekyll, Christian Camargo as zoologist Alexander Sweet; Jessica Barden as Justine, a young acolyte to Lily and Dorian; and Wes Studi as Kaetenay, an enigmatic Native American with “a deep connection” to Chandler.

Whether it's like his connection to Dorian Gray (Reeve Carney) we'll have to wait to see.

Watch the dark (in both senses of the word) teaser for Penny Dreadful's third season below.

Penny Dreadful returns to Showtime on May 1 at 10pm.
