Fortitude is a new twelve part drama for Sky Atlantic starting tonight with quite the impressive cast made up of Academy Award nominee Stanley Tucci, The Killing's Sofie Grabol, Christopher Eccleston (Doctor Who, The Leftovers) and Irish actors Michael Gambon and Richard Dormer. It's set in a beautiful Arctic town like no other in that the crime rate is pretty much at zero. That is until now, when a violent murder shakes the town to its core. The series, created by Simon Donald, will follow the investigation as everybody in this peaceful, close-knit community becomes a suspect. An Arctic Who Dunnit, essentially!
