Vic the Viking (2013)

Hagar plans to raid an Irish tribe, but his scouting party is overpowered while their laughter betrays them observing the local prime sport and mode of conflict-solving: a dance duel. To recover ship and freedom, Hagar must beat their chief in a dance battle. Wickie gets his rival to coach them, sees it still won't work and comes up with a semi-accidental invention to trade for their liberation.
