Sophie Turner and Kit Harington—who portrayed siblings on Game of Thrones—play lovers in their upcoming film The Dreadful, which made for a “really weird” experience.

Sophie Turner and Kit Harington famously played Sansa Stark and Jon Snow on Game of Thrones, cousins who were raised thinking they were half-siblings. Either way, they're related. But that didn't stop a lot of fans from fantasizing about a potential romance between the two,

Less than a decade later, The Dreadful will see Turner play Anne, an outsider who lives with her mother-in-law on the fringes of society when her harsh and solitary life is suddenly upended by the presence of a man (Harington) from their past, who sets off a sequence of events that become a turning point for Anne.
