Gaffer Tape's idea of a three movie story is a good one. Perhaps bringing back Blofeld (he was killed off in the series for legal problems with the character, which I belive can be easily solved now).

I also had two ideas for Bond movies: bringing back Richard Kiel, to reprise his role as Jaws. It would be a different timeline Jaws, since he was supposedly killed off in Moonraker (was he?). Another idea would be having a Bond film SET in the 60s. No modern-age Bond, a 1960s cold-war era Bond.
