The ensemble voice cast features Roger Carel and Jacques Frantz as Asterix and Obelix, with Paul Giamatti and Brad Garrett headlining the English dub.

This adaptation introduced new characters, anachronistic references about modern technology, and cover versions of pop songs, such as "Get Down on It" by Kool and the Gang, "Eye of the Tiger" by Survivor and "Super Freak" by Rick James.

The Viking's chief, Timandahaf, misinterprets his adviser's words and declares they must find a "Champion of Fear", believing that if the tribe were to become great cowards, they'll be able to fly and become invincible.

When the Vikings arrive near their village, Cryptograf explains to his incredibly stupid son Olaf that he could claim Abba as his wife if he were to capture the Champion, thus putting him next in line as the tribe's chief, with his father secretly calling the shots.

When the vikings test Justforkix's flying skills by throwing him from a cliff, Cryptograf secretly rigs up a rope to him that causes him to be suspended in the foggy air.
