Kit Harington has recalled the "embarrassing" moment when he had to kiss Sophie Turner in The Dreadful.

The 38-year-old actor had to stand on an "apple box" to give his gothic horror movie co-star - who plays Anne, the love interest of his alter ego Jago - a kiss because she is taller than him.

And shooting the scene felt "a bit weird" for the duo because they played siblings, Jon Snow and Sansa Stark, in the HBO drama, Game of Thrones.

Kit told E! News: "It was slightly embarrassing, having to get on an apple box to kiss her because she's about a foot taller than me.

"But other than that, my dignity was pretty intact."

The star felt uneasy when he discovered that he and Sophie's characters are lovers in The Dreadful.

Kit recalled: "She was one that sent that movie to me and somehow didn't see what I saw in it.

"I was like, 'These guys, these are lovers, right?' I felt very odd about that."

Nonetheless, he loved acting alongside Sophie, 29, again.

Kit said: "It was a good chance to be with her again and work together.

"What was lovely is that we got on set together and our friendship completely ignited again. It felt like being with family. It really did."

The Dreadful is "set in the 15th century during the Wars of the Roses" and sees "Anne and her mother-in-law Morwen exist on the outskirts of society when someone from their past re-enters their life".

It also stars Marcia Gay Harden (Morwen), Laurence O'Fuarain (Seamus), and Jonathan Howard (Brother Penros).

Elsewhere, Kit enjoyed working with 54-year-old actor Mark Wahlberg in the action-comedy film The Family Plan 2.

Kit - who plays Aidan in the Apple TV+ Christmas movie - told E! News: "It was gorgeous. I've seen his career and been like, 'That guy's extraordinary.' How he maintained his career over the years, how he maintained himself and his professionalism - he's a real inspiration."

However, Kit felt nervous being on set with Mark - who plays car salesman and ex-covert assassin Dan Morgan.

Kit recalled: "I was quite daunted working on set with him. The first day, we had to do a fight scene, and for me, that was a daunting thing. But he couldn't have been more welcoming. He's such a lovely, lovely man."

And Mark was thrilled to work with Kit in The Family Plan 2.

Mark said: "He's amazing, wonderful."

The Family Plan 2 - which sees Dan and his family go to Europe for Christmas, but his past comes to haunt them - is released on November 21.
