Winter Kills (1979)

Winter Kills (1979), is a wild, kaleidoscopic phantasmagoria of conspiracy theories piled on top of (and inside and all around) one another with ferocious black comedy and unflinching ambition. It is the story of Nick Keegan (Jeff Bridges), the brother of a none-too-subtly-JFK-like murdered president, who investigates the assassination and finds one cover-up after another, leading to more puzzles, dead-ends, and open questions than he could have imagined.

Jeff Bridges has aged well, but this is a chance to go back and see a young, fit Bridges at his sexy, skinlicious prime.  After having sex, he gets out of bed and starts walking across the room.  At first, the camera only shows his broad shoulders, but then…he turns and his shapely seat surfaces as he pulls on some tight white underwear.  The shot is brief, but full and satisfying.
