Showtime is ordering a second season of Penny Dreadful. The Victorian-era horror thriller starring Josh Hartnett, Timothy Dalton and Eva Green has been picked up for another round. The premium network is committing to 10 more episodes from writer-producer John Logan, an increase on the first season’s 8-episode order.

“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 tells 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.”

Nevins says the rest of the first season will involve a continued expansion of the world of the show and a deeper exploration of the current characters. “It just gets richer deeper and more complicated with the characters,” he says. “We’re only four episodes in and you’re only just getting a taste of what’s to come.” The first season will also provide closure to the current main story arc, involving the search for Sir Malcolm’s (Dalton’s) lost daughter.

Penny Dreadful has averaged 4.8 million viewers across all Showtime platforms since the show’s launch, with Penny ranking as the network’s most-watched new show ever On Demand. .”It’s done better on non-linear platforms like On Demand than any show we’ve ever had,” he says. The show will once again shoot on location in Dublin and is expected to debut season 2 next year.
