Not to mention though, he kind of seems quite tired and just walking through some of the scenes in Diamonds Are Forever. Or perhaps that he is more out of shape.Well I agree those elements that what makes YOLT good, but the film is not the kind of Bond film I personally like. There are so many high-tech gimmicks, and such an outrageous, and unlikely plot to comprehend with. Connery gives his most tiring performance ever. I can't blame him.Thunderball would be my second all time favorite Connery film after You Only Live Twice.. It was the first Connery film I ever saw, and the whole cinematography of Japan, the gorgeous score by John Barry and of course the awesome helicopter battle with Little Nellie, just made it the perfect Bond film for me.
I suppose you're right, Connery may be he most bored looking in You Only Live Twice, but he looked more fit in it than Diamonds Are Forever.
