About Ben Robson
Ben Robson plays Kalf in Vikings and Craig Cody in Animal Kingdom. The move between those roles takes him from a disputed earldom and Lagertha’s political world into a contemporary crime family. His film credits include Cole in The Boy and Ray in A Violent Separation, giving viewers further routes into his work outside historical television.
Animal Kingdom is the strongest next stop because it gives Craig room to develop within a continuing ensemble. The Boy is a shorter commitment and a change to horror. For someone who found Kalf interesting as a supporting figure, these choices make it easier to see Robson in a different narrative position rather than simply searching for another Vikings-like setting.
