He said this to the Huffington Post recently:
“I’m not a fan of the cameos in ‘Game of Thrones.’ I don’t like them. I think it’s stupid. I don’t mind going on the record on that. I just think it takes you right out of the world.
Especially Ed Sheeran. I was like, ‘Why is Ed Sheeran here?’ I mean, Ed Sheeran’s great. He’s a great guy, great musician, but why is he in ‘Game of Thrones’?
It was a big snap to reality. It’s a fantasy show. We’re all caught in this amazing world and spend so much time and money and talent to create, and all of a sudden there’s a pop star? What?”
