Anyone who knows that Never Say Never exists knows that it is a weird legal wrinkle and not a mainline bond film.
And Casino Royale is a fucking comedy that is clearly not in continuity and not considered a true bond film
I knew about the Peter Sellers Casino Royale, but not Never Say Never Again. Only thing I remember about it was that it was written by Rhold Dahl. Had no idea it was in some way "unofficial". Given that it stars Sean Connery, I'd have assumed it fell under the same umbrella as the other Bond movies.
For background, I have seen every Bond movie except the last one, have been watching them since I was a kid, and my controversial favorites are Live and Let Die, and The Man with the Golden Gun. I knew there was a funky thing with the movie rights, but always just assumed it was the George Lazenby flick. I'd be confused and irritated if I bought a set containing "all" the Bond movies, and found one of the Connery films was missing.
As for the number, I had no idea how many Bond movies there were until this thread; and I'd never have been able to name them all in order to double-check the list on the box from memory.
I wouldn't have been surprised if the set happened to be missing whatever the latest couple of films were; but to me, and I suspect most other casual fans who might care enough about the franchise to (try to) buy a complete set, "all" implies every Connery, Moore, Dalton, and Brosnan movie at the very least.
I call shenanigans.
