Speaking of remakes - and this is going to sound a bit daft - but my first impression on leaving the cinema after seeing Casino Royale in 2006 was that I'd just watched a very superior remake of an "official" Bond version of it I'd seen decades before. Except, of course, that no such official version of CR had been made, just the 1967 spoof and the 1954 US TV movie. I suppose it was the "reboot" aspect that made me think that - Bond at the start of his Double-O career and so on, but set in the 2000s rather than the 1960s.
Leaving the cinema in 1983 after NSNA I had no such first impression, even though this really was a remake of a "real" Bond film from 1965. And I think it's because whereas CR 2006 felt like the start of a new series of Bond adventures, for me at least, with NSNA what interested many I imagine was whether Sean Connery, twelve years on, could still do James Bond, rather than whether another team could do a better job of remaking a previous Bond film. It wouldn't have mattered if he'd appeared in a remake of any of the other Bond films, if that had been legally possible - the "hook" for the mass audience was always Connery. He proved he could still do it, but NSNA wasn't any better than TB, and in some respects was worse.
(Now, if someone had made a "proper" version of CR in the early 1980s with Sean Connery as Bond, with the whole "Bond begins" aspect of the story taken out, and instead 007 on one last mission focusing his renowned gambling skills on bankrupting Le Chiffre - that might have been interesting. Could it have been made? After all, EoN didn't have the film rights then.)
