When Sophie Turner read the script for "The Dreadful," she knew she wanted to do the movie with "Game of Thrones" co-star Kit Harington. What she didn't think about was how "dreadful" their kissing scenes would become.

Sophie Turner said she and her "Game of Thrones" onscreen brother Kit Harrington were "both retching" as they filmed their sex scenes for "The Dreadful."

Sophie Turner, 29, recently filmed a gothic horror movie, The Dreadful, with her former Game of Thrones costar Kit Harington, she shared on Late Night with Seth Meyers. Turner and Harington — who played siblings Sansa Stark and Jon Snow, respectively — discovered they had a few love scenes in the film, which was a nauseating prospect for the pair.
