Sophie Turner dishes on kissing co-star Kit Harington for new film

Primetime Emmy Award nominee Sophie Turner is starring in a new gothic horror movie, The Dreadful, with her Game of Thrones co-star Kit Harington, whom she “retched” to share a smooch with.

Speaking on Late Night with Seth Meyers, Turner said she and Kit found out they had a few romantic scenes in the film, which disgusted the duo.

The stars formerly played siblings, Sansa Stark and Jon Snow, in HBO's award-winning fantasy epic.

The X-Men franchise star shared that when she received the script for The Dreadful, which she is also producing, the director asked her who she believed would be a good fit for the film.

Kit “immediately” came to Turner’s mind.

She shared the script, and Kit agreed with her that it was a great project. Though Kit, having some reservations, responded, “Yeah, I’d love to, but this is going to be really f------ weird, Soph."

When Turner looked at the script, it was loaded with intimate scenes and multiple kisses.

"I'm like, 'Oh, shoot ... that's my brother,'" Turner said. "But it's such a good script that he was like, 'We kind of have to do it.'”

However, Turner recalled the first scene where they had to film their characters kissing. "We are both retching," Turner said. "Like really, it is vile — it was the worst."
