  ===Casting===
  This episode introduces the character of Samwell Tarly, a new recruit of the Night's Watch and a self-described coward. John Bradley was cast in the part, the actor's first professional appearance after graduating from the Manchester Metropolitan School of Theatre. The scene used in the auditions belonged to "Cripples, Bastards, and Broken Things," with Sam explaining to Jon how his father forced him to take the black. According to author and executive producer George R. R. Martin, Bradley delivered "a heartbreaking performance."
  Australian actor Conan Stevens, whose official website lists his height as 214 cm (7' 1/4"), first appears as the gigantic knight Gregor Clegane, known as "the Mountain." Stevens had sought to join the production since HBO started developing ''Game of Thrones''. Since the character of Gregor Clegane, the role he believed he was most fitted for, did not appear in the pilot, he auditioned for the role of Khal Drogo instead in the hopes of getting noticed by the casting team. Although that role went to Jason Momoa, Stevens was chosen for the part of Gregor.
  Other recurring roles making their first appearance in the episode include Dominic Carter as commander of the City Watch Janos Slynt, Jerome Flynn as the mercenary ("sellsword") Bronn, and Joe Dempsie as the smith's apprentice Gendry. The character of Gendry was made older for the series than he appears in the books.
