I love this idea.
Already happening on radio, btw: Toby Stephens (the villain in Die Another Day) has played Bond twice for BBC Radio Four, with David Suchet as Dr No, and Ian McKellen as Goldfinger.
Bond has been adapted for radio? I never knew that and I LOVE radio shows (got a CD collection of them almost as large as my DVD/VHS collection). Are these availale on CD, or for download somewhere?
Looking at the BBC shop, it doesn't seem as if they're avalable on CD. That might change, as while Dr No went out in 2008, Goldfinger was only run a bit over two weeks ago, on April 3rd. Goldfinger would have been on the BBC Listen Again site for a week after transmission, but is probably gone now - might be worth checking just in case?
Initially Dr No was supposed to be a one-off that Eon allowed to mark Fleming's 100th anniversary, but clearly they've relented so hopefully there'll be more to come.
So far, other cast members have included Patrick Stewart's ex, Lisa Dillon (as Honey Ryder), Rosamund Pike as Pussy Galore, plus Martin Jarvis, Peter Capaldi, Clarke Peters, Simon Williams, Lucy Fleming (Fleming's niece and literary heir) and Ian Ogilvy.
