'Vikings' series four is being written right now. Michael Hirst, the series' creator, confirmed to Radio Times that he is penning a fourth series of the show, which airs on History. Not only that, he reckons it could have a lot of life left in it yet.
"I've written five episodes [of season four]," he said. "We're going to do more episodes this year, I think we're doing 16. I have a huge hope that we can continue."
The series focusses on the real character of Ragnar. But even after he meets his maker, his sons could easily take over as stars of the show.
"I always anticipated continuing with Ragnar's sons because many of them became as famous, if not more famous, than he was," Hirst said.
"There was the rather remarkably named Ivar the Boneless and Ragnar's elder son [Bjorn] who sailed around the Mediterranean, and then they went to Iceland and Greenland.
"So much happened in the early years of the Vikings it's incredible, which is why I wanted to start at what was essentially regarded as the beginning of the Viking age."
'Vikings' series two started on History on Tuesday. The third series is currently landing episode-by-episode on Amazon Prime Instant Video.
