From httwww.bond23.net:

After fan speculation about the role that young English actor Ben Whishaw will play in the 23rd James Bond film, Skyfall, his agent confirmed to the BBC that Wishaw would play “Q”, the MI6 Quartermaster played for over two decades by Desmond Llewelyn.

The role also went to Monty Python star John Cleese for a single outing, Die Another Day.

It will be the first time that 007 is older than his gadget master, and it looks as if the creatives behind Skyfall are looking for a completely new direction for the Quatermaster – rather than attempting to recreate the popularity of Llewelyn’s long-serving character.

Good for him!
