While the actual source of the news is unclear, the British newspaper seems pretty sure that early talks have commenced between Nolan's people and Bond producers Barbara Broccoli and Michael G. Wilson. Nolan is currently in pre-production on Interstellar, a sci-fi epic exploring gravity fields and wormholes starring Matthew McConaughey, Anne Hathaway and Jessica Chastain. That will keep his tied up until the end of next year, and the Bond camp will be looking to build on the momentum of Skyfall's success and get their follow-up into development as soon as possible.
While it's unlikely that Broccoli and Wilson will want to wait until probably 2016 for their next film, there is nothing to stop Nolan taking a crack at Bond at a later date. With Daniel Craig signed on for two more outings, perhaps Nolan could be lined up for Craig's swansong as 007, as he's expressed in the past that he's a fan of the actor's work.
The big question of course is whether or not Nolan is suitable for the Bond franchise. The Dark Knight and Inception director is often criticised for the way he stages action, but there's no denying he has a flare for the spectacular - something the Bond series will be looking to continue after its next-level last outing. But since when has Bond been about the directors? Arguably the hiring of Sam Mendes was the first and only time in the series' 50-year history that a "prestige" director has been brought on. Would this kind of trend be beneficial, or ultimately detrimental to the Bond canon as a whole?
