As we previously mentioned, "Vikings: Valhalla" takes place 100 years after the original, so don't expect to see any characters from the History series. Starring in "Vikings: Valhalla" is Sam Corlett as Leif Eriksson, Frida Gustavsson as Freydís Eiríksdóttir, Leo Suter as Harald Sigurdsson, Laura Berlin as Emma of Normandy, and Bradley Freegard as King Canute The Great. These five will lead the charge on the series, but they're surrounded by a stellar supporting cast.

The ensemble also includes Jóhannes Jóhannesson as Olaf "the Holy" Haraldsson, David Oakes as Earl Godwin, and Caroline Henderson as Jarl Haakon. Other recurring characters include Pollyanna Mcintosh as Queen Ælfgifu of Denmark, Asbjørn Krogh Nissen as Jarl Kåre, Julian Seager as Jarl Gorm, John Kavanagh as The Seer, Pääru Oja as Arne Gormsson, and Louis Davison as Prince Edmund.
