Robert Louis Stevenson’s Dr. Henry Jekyll will join the show’s line-up of literary characters in Season 3. The infamous character will be played by Shazad Latif (The Second Best Exotic Marigold Hotel), who played data analyst Tariq Masood in the final three seasons of BBC One spy drama Spooks.

Patti LuPone (American Horror Story), who guest starred in the second season as the Cut-Wife, will be back as a series regular in the new role of Dr. Seward, an American therapist who treats Vanessa (Eva Green) with an unconventional new approach.

Other new guest stars will include Christian Camargo (Dexter) as Dr. Alexander Sweet, a zoologist who strikes up an unlikely friendship with Vanessa; Sam Barnett (Jupiter Ascending) as Dr. Seward’s mysterious young secretary; Wes Studi (Hell On Wheels) as Kaetenay, an intense, enigmatic Native American with a deep connection to Ethan (Josh Hartnett) who also becomes an ally to Sir Malcolm (Timothy Dalton); and Jessica Barden (The Outcast) as Justine, a young acolyte to Lily (Billie Piper) and Dorian Gray (Reeve Carney).

Billie Piper, Simon Russell Beale and Harry Treadaway are also return returning.

Season 3 will air on Sky Atlantic in 2016.
