Austin Powers borrowed a lot from the original Casino Royale (the 60s spoof version), and the classic 60s spoof duology In Like Flint/Our Man Flint (fun watches that still hold up; Austin Powers even directly name drops them). Those 60s spoofs didn't kill campy/fun James Bond, and also show us evidence of this sort of spoof/serious cycle in Bond (and elsewhere) is likely cyclical. If history is to judge, we're about to the point where Austin Powers flutters out of collective consciousness again and given the right actors/directors/producers the Bond movies can do fun stuff again.
