"The goal here was to see if we could do a genre show a horror show but with all the sophistication and depth of a Showtime show and John Logan ended up being the person to do it," Showtime president David Nevins told EW. "It's been well reviewed by mainstream critics, it's giving us a Comic-Con-appeal show. It's a whole new world as imagined by Logan."

"It just gets richer, deeper, and more complicated with the characters," he added. "We're only four episodes in and you're only just getting a taste of what's to come."

"Penny Dreadful" stars Josh Hartnett, Timothy Dalton and Eva Green; season 2 will go into production later this year and will again shoot on location in Dublin for a 2015 launch, according to Deadline.
