According to the Daily Mirror, a senior executive has confirmed that "exploratory talks" with the actor took place, after he was sworn to secrecy about Jon Snow's return to the series.

"Any spin-off built around Jon Snow, who is hugely popular with fans, would also undoubtedly involve other characters from the cast," a source said.

"When the final season wraps next year, it's going to be a case of figuring out who we want to join us for a new series and which of those cast members actually want to jump on board."

The series is reportedly set to launch if the HBO show comes to an end next year. If Harington signs on it could make him one of the highest-paid stars in TV history.
