Sophie Turner found it "weird" to play Kit Harington's lover in a movie

Speaking in a video interview with Vogue, she said: "I did a movie last year which I'm really excited about with my old but very good friend Kit Harington, who played my brother on Game of Thrones.

"We're doing a gothic horror... but we play lovers."

Sophie then grimaced as she apologised to viewers.

She said: "Sorry, guys. It's really weird for all of us."

Game of Thrones featured incestuous relationships and Sophie had previously teased "things could happen" between Sansa and Jon, particularly after his true parentage was revealed, but she admitted she would find it awkward.

Speaking in 2016, she told Access Hollywood: "Things could happen, things couldn't happen. They are cousins and it is Game of Thrones.

"I could not do that with Kit. There's no way I could do those kind of scenes with Kit- I'd laugh way too much."

Despite finding it "weird" playing lovers in The Dreadful, which is set in the 15th century during the War of the Roses, Sophie previously admitted she pushed producers to cast Kit, 38, opposite her.

She told the Sunday Times newspaper: "They were trying to find someone for that role, and I was like, 'You can't not have Kit.'

"It's set around the time of the Wars of the Roses, so we'll probably be floating about in robes on clifftops again."

Sophie - who has Willa, four, and three-year-old Delphine with ex-husband Joe Jonas - previously joked she "got [her] sex education" from Game of Thrones.

During an appearance on the Dish podcast, she quipped: "I definitely got my sex education from that show. More than enough."

Sophie also likened her castmates to family members.

She explained: "I never had proper formal training, so I got to learn from the amazing actors around me, which I felt like I won a competition. But it was great. We all were a family.

"My character, I got to live with. So it felt like we kind of merged into one person by the end of it. But it was amazing."

Sophie admits that the show "informed [her] entire life in terms of like business decisions, just etiquette on set, how to act".

She added: "Everything I learned from Game of Thrones - and a bit from my parents."
