About Jasper Pääkkönen
Jasper Pääkkönen plays Halfdan in Vikings, but his film work is an important part of the story beyond Harald’s brother. His credits include Matti Nykänen in Matti: Hell Is for Heroes, Harri in Heart of a Lion, Felix Kendrickson in BlacKkKlansman and Seppo in Da 5 Bloods. Omerta 6/12 adds a different kind of screen role as Max Tanner.
Heart of a Lion also connects his filmography with that of Peter Franzén, the actor who plays Harald. That makes it an especially useful follow-up for viewers interested in both performers. BlacKkKlansman and Da 5 Bloods offer routes into his work with Spike Lee, with very different settings and character functions from Halfdan’s place in the saga.
