The first part (of 5) of the GOT Comic-Con panel is up on YouTube!
‪(1 of 5) Game of Thrones, San Diego Comic Con 2011‬‏ - YouTube
The discussion was lead by GRRM and featured Nikolaj Coster-Waldau, Kit Harrington, Lena Headey, Peter Dinklage, Joson Momoa, Emilia Clarke and the producers, David Benoiff and and D.B. Weiss. I have to say, Nikolaj and Kit looked particularly yummy.
Hopefully, the next 4 parts will be up soon!
