It reminds me of people on Reddit trying to analyze things like how Superman flies. Superman’s flight can’t be explained by science. It’s a metaphor. It represents a psychological truth, not a scientific one. You should think about what flight means, how it makes you feel, not the mechanics of it.

If it were me, I’d do a Bond set in the 1960’s…then the next one in the 40’s during the war. Literally who cares? Do whatever you want, audiences will accept it. The only crime with Bond is to be boring or repetitive…the more novel you can go, the better.
