ITV's Beowulf: Return to the Shieldlands is being eyed as a long-running series - with cast-members signed up for five series.
Da Vinci's Demons actor Kieran Bew plays the title role in the epic fantasy series, with Downton Abbey's Ed Speleers cast as his rival Slean.
Speleers told press including Digital Spy that he's excited to embark upon what could be a long-term project.
"There was a time I didn't work for months so the fact that someone wants to offer me a five-year contract... a lot of people would look at this as being tied down but I take it as a compliment," he said.
"They want me to be a part of this thing and that's a positive. It's a massive role and I have never before had a chance to play a part like this ever - and there's always time to do a few things on the side."
Based on the classic poem, and also starring William Hurt and Joanne Whalley, Beowulf has been described by co-creator Katie Newman as "one of ITV's biggest ever shows, and incredibly ambitious".
"I hope this goes on for years and years - and that this is just the beginning," said Speleers.
Beowulf: Return to the Shieldlands begins tomorrow night (Sunday, January 3) at 7pm on ITV.
