Two-time Tony Award® winner, Patti LuPone (American Horror Story, Life Goes On, Evita, Gypsy), captivates this week's episode of PENNY DREADFUL in a special guest appearance on Sunday, May 17 at 10PM ET/PT on SHOWTIME. View an exclusive scene from the episode below!

In this special flashback episode, Vanessa (Eva Green) meets The Cut-Wife (LuPone), who teaches her how to harness her powers. While the two are isolated at a lonely cottage on the moors, the Cut-Wife quickly realizes the extent of Vanessa's POWERS and warns her of the danger that lies ahead and the evil that pursues her.

From three-time Oscar® nominee John Logan, PENNY DREADFUL's second season finds Vanessa Ives (Green) and Ethan Chandler (Josh Hartnett) forming a deeper bond as the group, including Sir Malcolm (Timothy Dalton), Dr. Frankenstein (Harry Treadaway), and Sembene (Danny Sapani), unite to banish the evil forces that threaten to destroy them. Meanwhile, Dorian Gray (Reeve Carney) and the Creature (Rory Kinnear) are all waging battles of their own. LuPone, a special guest star, plays a mysterious character of great importance in Vanessa's past. Helen McCrory returns as Evelyn Poole (a.k.a. Madame Kali), the seductive spiritualist who will pose a unique threat to our protagonists this season, along with Simon Russell Beale, who is back as eccentric Egyptologist Ferdinand Lyle. Additional guest stars include Douglas Hodge as a Scotland Yard investigator and Sarah Greene as Poole's powerful daughter, Hecate. PENNY DREADFUL is created, written and executive produced by John Logan (Hugo, The Aviator, Gladiator) and executive produced by Logan's Desert Wolf Productions, along with Oscar winner Sam Mendes (American Beauty, Skyfall) and Pippa Harris (Revolutionary Road, Call The Midwife), both of Neal Street Productions. A co-production with Sky, PENNY DREADFUL was shot on location in Dublin, Ireland.
