Mr Kiss Kiss Bang Bang
You can keep today's Blooms, Pitts, Diesels and Timberlakes. For me, nothing beats Sean Connery. A former nude model, sailor, coffin polisher, milkman and 3rd in the 1953 Mr Universe contest, in his films Sean was often cast as an odd mixture of suave sophistication and animalistic instinct. In the Bond films for example, he's impeccably clad in a dinner-jacket but happy to kill given a second's notice. The producers cast him because they liked how such a big man could move so gracefully.
In the Hitchocock classic Marnie, he plays Mark - a classy hero - who wants to help psychologically disturbed Marnie - until his lust gets the better of him, and he rapes her, causing her to attempt suicide. In Zardoz, he's a leather-thonged, hairy barbaric killer, plaything of the Eternals, who experiment on him, trying to see what will give him an erection. But he learns to read in a matter of days and has a huge epiphany during The Wizard of Oz.
So what if he wore a toupee during many of his films, he was still being voted Sexiest Man Alive well into the 1990s. I'll be dusting off my early Bond DVDs over the Christmas period and watching them all over again. They may be silly (and sometimes the Austin Powers take-offs are almost directly lifted - more remake than parody), and unpolitically correct. But I love 'em.
