Ramsay was almost Jon Snow
Iwan Rheon, who in “Battle of the Bastards” fought Jon Snow, nearly played the character.
“I auditioned for the pilot of ‘Game of Thrones’ and was down to the last two for Jon Snow.”
As IMDb explains: “He obviously didn’t get the role that went to Kit Harington, but when he was eventually cast as Ramsay, the producers just gave him the character of ‘Boy’ so as to avoid spoilers about who he was really playing.‘I wasn’t allowed to talk to anyone about it from the beginning of filming to the broadcast of the end of Season 3. I was supposed to say to everyone, ‘Oh, my character is Boy,’ which was really embarrassing.’
