Speaking to TMZ, he said he’d be happy to see an alternate ending, saying it would be “cool”.
His words follow an online petition set up by irate fans frustrated by how the series was concluded.
Reflecting generally on working on Game of Thrones, Chapman told Esquire: “When I stepped on set, I compare it to walking round Disneyland, seeing all the characters, seeing all the sets because I was a genuine fan.
“They were such good actors and I was only a kid, so I was a bit intimidated. I didn’t realise at the time how good I had it.
“I always wanted more from the character. I was a bit like, ‘Let me do something!’ but I look back now and see it as one of the best things I’ve done.”
Game of Thrones is available to buy on Blu-Ray and DVD now.
