Actor Kit Harington was uneasy filming sex scenes on `Game of Thrones` with his good friend Emilia Clarke.

The 36-year-old actor viewed his `Game of Thrones` co-star as one of his best friends so although it wasn`t "hard" shooting scenes in the final season of the show where the relationship between their characters Jon Snow and Daenerys Targaryen turned romantic, they often got the giggles and ultimately found it quite "weird", reports femalefirst.co.uk.
