You know him as Samwell Tarly in "Game of Thrones," but when he's not being the most unloved member of the Night's Watch, he's actor John Bradley. The actor joined Steven Smith during San Diego Comic-Con.
"In terms of Sam, the two questions you get most asked the most is 'Why did you drop the Dragon Glass there,' and 'Why is Sam still so fat?'" Bradley joked a bit about fans' responses to his character on the show, perhaps not the bravest man in Westeros, but certainly the most earnest. Bradley is able to shrug off some of the less fun things fans say online, adding that he simply takes their jabs as comments at Sam the character and not John the actor (be nicer on the Internet, though, you guys).
He also talked a bit about the reactions to "The Red Wedding" sequence, describing the YouTube reaction videos as "intense." As a fan of the books (as well as being on the show), he was one of those viewers who waited on the edge of his seat for reactions for those who weren't familiar with the source material. Plus, did you know the drummer from Coldplay was knocking around in that scene?
The fourth season of "Game of Thrones" is currently in production.
