Something's Gotta Give (2003)

One of the prime differences between men and women is that the ladies have a wholly unrealistic idea of what it means for a guy to act his age. The female notion of male maturity (developed as the winsome lass moves through the stages of supple youth toward a ripe and randy middle age) insists that an emotionally adult fellow will find his greatest sexual fulfillment within the arms and thighs of a gal from his same generation. Such is the view posited and championed by Something's Gotta Give (2003), a film that depicts the love affair of two spritely sixtysomethings, Harry Sanborn (Jack Nicholson) and Erica Barry (Diane Keaton). Both Nicholson and Keaton turn in nudie moments in this movie (Nicholson’s is during a comedic moment -- he groggily stumbles out of a hospital room, his open gown revealing his butt),. It’s a pretty momentous event, given both their status as screen legends.
