Kit Harington and Sophie Turner laugh and gag after kiss in new outtake

Kit Harington and Sophie Turner, best known for playing on-screen siblings in Game of Thrones, seem unable to shake those family ties. In a behind-the-scenes outtake from their new horror film The Dreadful, the two share a kiss and then immediately start to laugh and gag when the director calls "cut." The clip has gone viral on Twitter, picking up more than 95,000 likes.

Directed by Natasha Kermani, The Dreadful is set in the 15th Century and follows two women—Anne (Turner) and her mother-in-law Morwen—whose lives are upended by the arrival of a man from their past. The cast also includes Marcia Gay Harden and Laurence O'Fuarain.

The Dreadful arrives in theaters on February 20. Harington and Turner's Game of Thrones characters, Jon Snow and Sansa Stark, were raised as siblings (or half-siblings) but were actually cousins, with Jon revealed to be the child of Lyanna Stark and Rhaegar Targaryen.
