Comic-Con 2012: 'Game of Thrones' Confirms 14 Season 3 Cast Additions (Video)

"The Avengers'" own Emma Peel, Diana Rigg, is among the long list of new faces introduced during the panel, prompting George R.R. Martin to joke about killing off the current players.

Before slinging questions at some of the current cast members of HBO's Game of Thrones, writer George R.R. Martin kicked off Friday's Hall H panel by playing an introductory reel to 14 of the series' many new additions for the third season.

Many of the names had previously been reported, but fans started screaming when the slew of actors spoke about the significance of joining the series.

Leading the list of familiar names was Diana Rigg. The 73-year-old actress, best known for her work as Emma Peel on iconic '60s TV series The Avengers, will play Olenna Tyrell, "The Queen of Thorns."

"Diana Rigg as The Queen of Thorns," said Martin, whose commentary and line of questioning frequently focused on innuendo. "I flash back to my youth and all of my days watching The Avengers."

Readers of the books know Olenna is the grandmother of Margaery and Loras Tyrell.

Mackenzie Crook, best known for the British Office and The Pirates of the Carribean movies, will play wildling raider Orell.

Richard Dormer will play another member of Brotherhood Without Banners, Beric Dondarrion.
