Long before the Brokeback boys made the gay cowboy cinema-chic, Jon Voight rounded up a herd of controversy for his breakout role as rustler/hustler Joe Buck. This classic follows the charismatic, yet naïve Joe, who quits his gig as a Texas dishwasher to pursue a life of high-profile prostitution in the Big Apple. However, it's not long before poor Joe realizes first-hand how the "mean streets" got their name and his big-time dreams become a big-time disappointment. That is until he befriends a sickly street-saavy con-artist named Ratso Rizzo (Dustin Hoffman), who agrees to help him find some sex-starved clients. But as Ratso's health declines, Joe is forced to make dark choices and face even darker consequences. Hailed as one of the greatest American films ever, it's no surprise the film took home the Best Picture Oscar - but what might surprise you is that it's the only X-rated film to do so. Oh, and keep an eye out for Dustin Hoffman's signature line-turned-New Yorker battle cry "I'm walkin' here!"
