Hirst confirmed: “In the script, I killed [him] off three times, and couldn’t do it. I couldn’t do it.
“He did lots of bad stuff that guy, but he did it so well and he had a sense of humour and I just didn’t want to lose that.”
Harald was presumed to have died at the end of season five, but made his surprising comeback at the beginning of Vikings’ latest instalment.
Despite Michael Hirst’s aversion to killing off beloved characters, fans are still anticipating a bloodbath in the second half of season six.
Vikings seasons 1-6 are available to stream on Amazon Prime Video.
