As fans await more news on the Game of Thrones prequel series HBO has planned, one actor has confirmed he won't be returning for the spinoff: Kit Harington.

The actor who portrays Jon Snow has made it perfectly clear that he's done with the world of Westeros when the series wraps after its eighth season.

“It was emotional to leave the job definitely,” Harington said to BBC News. “But I wouldn’t say I was sad: if like me you go all the way back to the pilot of ‘Game of Thrones’ that’s almost 10 years of your life–that’s really unusual in an actor’s career. It was a huge emotional upheaval leaving that family. But would I want to go back and do more? Not on your life.”

The current project, produced by Jane Goldman and George R.R. Martin, is set 5,000-10,000 years before Jon came into existence, and is currently in the casting stage. That hasn't stopped fans from wondering if there will be any flash-forwards or cameos, or even if Harington could play an ancestor of Jon, but the actor is steering clear of that.

According to the BBC, he’s enjoying stage-work too much and isn't interested in the prequel, which begins filming in February and has been tentatively called "The Long Night."
