Watch: 'Game Of Thrones' Audition Reel Revealed [Comic-Con 2015]

The casting on Game of Thrones is so perfect, it's hard to imagine there was ever a time before Gwendoline Christie was Brienne, for example, or Pedro Pascal was Oberyn Martell. But of course there was. At one point, Christie, Pascal, and all the others were just actors competing against countless others for a role.

At the Game of Thrones Comic-Con panel on Friday, HBO unveiled an amazing audition reel showing us how actors like Christie, Pascal, Natalie Dormer, Liam Cunningham, Tom Wlaschiha, and more got their gigs. Watch the Game of Thrones audition reel after the jump.
