Penny Dreadful has already been likened to Alan Moore's League Of Extraordinary Gentlemen, and those comparisons are going to become more frequent now that they've added Dr. Jekyll to the mix.
According to Variety Shazad Latif (The Second Best Exotic Marigold Hotel) will play an interpretation of Robert Louis Stevenson’s Dr. Henry Jekyll, and most likely his murderous alter-ego Mr. Hyde at some point, too. The site also reports that Patti LuPone, who played Joan Clayton (aka the Cut-Wife) season two, will be returning as a different character: Dr. Seward, who will treat Eva Green’s bewitched Vanessa Ives with an “unconventional new approach.”
Other new additions include Wes Studi as Kaetenay, "an intense, enigmatic Native American with a deep connection to Ethan (Josh Hartnett)", and Christian Camargo as Dr. Alexander Sweet, "a zoologist who strikes up an unlikely friendship with Vanessa."
Penny Dreadful returns with 9 new episodes in 2016.
