But that's why I think Cleese as R would be funny, because he never really was R. It would be neat to have him back in a demoted or secondary capacity and be called R again, as he was previously the Q. Or he could be R and look at the fourth wall, like Didn't I already do this with the other guy? Just a nice joke about the screwyness of rebooting the 007, but no one else apparently.
Actually, today they could just recreate Desmond Llewellyn if they wanted. They could have had a Moneypenny all along. A little bit of humor from her is what Craig's films have thus far been lacking.
