We only know about this happened because somebody hacked Sony's emails and published them on the web, so we feel a little naughty about using this information. It's out there in the public domain, though, so we're going to go with it! The part of Agent C in the James Bond movie 'Spectre,' as so memorably played by Andrew Scott, was originally penciled in for Chiwetel Ejiofor. Not only that, Ejiofor would have earned $1m more than Scott if he'd agreed to do it.
There's no recorded reason as to why Ejiofor turned down the role, but we have a suspicion. At the time, there was a lot of speculation that 'Spectre' would be Daniel Craig's final 'Bond' film. Ejiofor was one of the names linked with the role in the press. If he'd taken it, he'd have been out of contention. Given that Craig decided to stay on and make another film, Ejiofor now has cause to regret that decision.
