The Northman boasts an excellent cast, including Nicole Kidman. Here is who each actor portrays in the film & in what other projects they've been in.

The Northman’s full cast and character guide. Directed by Robert Eggers from a screenplay he co-wrote with Sjón, The Northman is a highly-anticipated action-adventure that draws from Viking lore. The story and legend of Amleth is one that has influenced William Shakespeare’s Hamlet and is a true tale of revenge, violence, and reclaiming the throne.

The Northman follows Amleth, a young Viking prince who loves and is devoted to his father, King Aurvandill. Upon his arrival home after being at war, Aurvandill feels confident that Amleth is ready to finally become a man and take on the responsibilities that will shape him into a king one day soon, replacing his father and continuing the family line. However, before any of that can really happen, King Aurvandill is killed by his brother and Amleth is forced to flee to avoid the same fate. Angry, Amleth promises to get his revenge on his uncle for the murder he committed, and does everything in his power to find him and restore his family’s name.

The Northman brings together a great cast, with plenty of familiar faces from across TV and movies. Here is a full guide to the film’s characters, the actors who portray them, and in which projects the audience has seen them in before starring in the Viking epic.
