Game of Thrones Season 8

Game of Thrones' Season 8 star Isaac Hempstead Wright says his mom had to give him the sex talk early because of Bran's iconic scene on episode one

During a Wednesday appearance on ABC's "Jimmy Kimmel Live," Isaac Hempstead Wright reminisced about being cast as Bran Stark on HBO's "Game of Thrones" when he was just 10 years old.

Of his character's infamous scene at the end of the series premiere, when Bran was pushed out a window after witnessing Jaime and Cersei Lannister, who are twins, having sex, Hempstead Wright said, "I was pretty much told what was going on.

"But it just sort of meant that my mum had to give me the sex talk a little earlier," he continued. "And with some sort of topics that probably aren't covered by general sex talks."
