Who directed the vikings 1978?

The only verified source supplied concerns the German‑Japanese animated series "Vicky the Viking," which premiered in 1974 and contains no details about a 1978 film or its director. Because the evidence does not mention a 1978 Vikings movie or any director associated with it, I cannot provide an answer based on the available information. If you are looking for details about a different Vikings production from 1978, additional sources would be required to confirm the director.
