Strangelove is a terrific film, despite the B52 exteriors-flying over the arctic which clearly show an aircraft shadow which is of a B29, but a model B52 matted onto it. But the B52 interiors look superb to me although guys who actually know the plane can always point out 'you can't get there from there' bits in movies.
In Thunderball, if I remember correctly, there's access from the rear crew position to the bomb bay. Not a feature of the actual Vulcan I think.
For more modern films, Dark Blue World is a good story of Czechs who came to england to fly in the BoB, I think a lot of flying footage is reused from the BoB film we all know.
