All it took to get Rory Kinnear on board for Penny Dreadful: City of Angels was a two-word email subject line. Kinnear, who played Frankenstein's Creature in the first Penny Dreadful, returns for City of Angels as an entirely different character — this time, he's the doctor. It's a role that really cuts down on his time in the makeup chair, which Penny Dreadful and City of Angels creator John Logan knew would be a selling point.
