Hats off.
Just a brief observation. Every James Bond movie usually has an opening sequence of circles ... and James Bond appears in one of the circles, firing a gun ... a signature opening for the films. But until "Live and Let Die," James Bond was always wearing a hat in that opening sequence. This movie is the first Bond movie where the opening sequence shows him NOT wearing a hat. In 1971's "Diamonds Are Forever," Bond does wear a hat in that opening sequence.
Art imitates culture (grin). Sometime in the late 60s and early 70s, the idea that a businessman should wear a hat fell out of favor culturally. And it's not likely to come back in style anytime soon.
P.S. I'm still waiting for one other idiocy to fall out of favor - businessmen wearing "sportcoats" and/or "ties." Neither a hat nor a tie serves any valid purpose and only serves to continue a tradition of silly conformity that makes no sense wardrobe-wise.
