It might be standard fare for siblings to hook up in George R.R. Martin's universe, but former Game of Thrones star Sophie Turner has expressed how she and her old on-screen brother, Kit Harington, were dry-heaving on set after their recent reunion in the upcoming horror, The Dreadful, which houses their first on-screen kiss together.

Kit Harington reveals the uncomfortable truth behind filming the iconic Game of Thrones dragon riding scene, describing the experience as "horrific."

Game of Thrones fans were pretty excited to hear that co-stars Sophie Turner and Kit Harington would be reuniting on-screen for a new movie, but the dynamic between the two will be extremely different and maybe even uncomfortable.
