Really, once you go trolling through movies for nude scenes, you realize how miserable the cinema has become. Despite being directed by Oliver Stone and featuring Sean Penn, Nick Nolte, Billy Bob Thornton and Joaquin Phoenix, U Turn bites. Luckily, Stone cast a then up-and-coming J. Lo, who's now trying to revive her sagging post-Bennifer career in the new movie An Unfinished Life. And perhaps sensing he needed something to revive his flagging film -- Stone convinced her to get nude. But before Lopez drops her top, she strips down to a black negligee for a non-nude sex scene with a haggard, ill-looking Nick Nolte. J. Lo plays Grace, a small-town fortuneteller and gold digger who figures Bobby (Sean Penn), a gambler with a sack of cash, might just make an easy mark. In a flashback scene late in the film featuring Grace in bed with a series of lovers, you see Lopez topless twice, her breasts in full view twice -- if only for a second. Or an hour, if you reach for the pause button.
