Former Bond girl Dame Diana Rigg will join the cast of Game Of Thrones for the upcoming season three.

IndieWire is reporting that the former star of cult spy show The Avengers will appear as Olenna Redwyne, The Queen of Thorns. Olenna is said to be a powerful and manipulative woman who comes to King’s Landing for her grand-daughter Margaery Tyrell (Natalie Dormer)’s wedding to King Joffrey.

New cast members are expected to make an appearance at the Game Of Thrones Comic-Con panel later today, and the 73 year old Dame could be among them.

Rigg will also be guest starring with daughter Rachael Stirling in an upcoming episode of Doctor Who, written especially for them by Sherlock co-creator Mark Gatiss.
