TV Guide has unveiled a new featurette for "Penny Dreadful" that goes behind the scenes of the second season of Showtime's Gothic thriller.

"This season, the hunters have no become the prey," Josh Hartnett teases as we see medium Madame Kali (played by Helen McCrory), already confirmed as the season's primary human protagonist. However, it appears she'll be accompanied by witches, who are determined to lay claim to the soul of Vanessa Ives (Eva Green).

"The demon within all these characters is the thing that makes them exceptional," creator John Logan explains. "That's what Season 2 is about."

"Penny Dreadful" returns Sunday, May 3, at 10 p.m. ET/PT on Showtime.
