The character of Q did not appear in 2006's "Casino Royale" or its sequel, "Quantum of Solace" (2008). Bond actor Daniel Craig expressed concern over the character's absence, and expressed his hope that Q would return in "Skyfall". In November 2011, it was announced that British actor Ben Whishaw had been cast in the role. Bond first meets Q in front of a painting at a museum, where he at first expresses disbelief at the relative youth of his new quartermaster, but the two quickly earn each others' respect. In "Skyfall", Q's gadgets were comparatively simple, consisting of a miniaturized radio and a gun coded to Bond's palmprint so only Bond could fire it. When Bond appears a little disappointed, Q comments 'Were you expecting an exploding pen? We don't really go in for that anymore,' in reference to a miniature grenade featured in "GoldenEye". Q is demonstrated to be highly knowledgeable on the subject of computer security to the point where he designed some of the most sophisticated security protocols in existence. However, he is also somewhat short-sighted; while engrossed in the puzzle of a security system set up by Raoul Silva, the film's main antagonist, he is unaware that he is inadvertently facilitating Silva's escape from MI6 custody until Silva actually escapes. As with Desmond Llewelyn's Q, he also gets frustrated with Bond's knack for damaging or destroying the gadgets – at the end of "Skyfall" the Aston Martin DB5 is burned out in the final showdown with Silva.
