One of the billboard ad taglines for the series is "#DontKillSeanBean", a reference to Sean Bean's roles where his characters often die in a violent manner.

Sean Bean's character in Game of Thrones was Lord Eddard Stark, who's sister, Lyanna, was played by Aisling Franciosi

In season 2 finale Martin Odum(Sean Bean) discovers he is really Alexei Volkov. His parents were named Alec and Natalya which harkens to Bean's appearance in GoldenEye where he was Alec Trevelyan and actress Izabella Scorupco played Natalya Simonova.
