An Irish casting website is "seeking leg only, male amputees" for a major battle scene in season three of Game of Thrones. Sorry Buster, better luck next time. For those who have read ahead, this means GoT is filming the "Red Wedding."
The notice goes on to caution,
You must be OK and comfortable with filming a scene within the context of a battle where your leg has been injured. Prosthetic makeup will be applied as though your leg has newly been severed. We understand that this is not for everyone, so please only apply if you are happy to participate.
