In the late 1960s and early 1970s, a whole group of films was released that brought two contrasting male characters together to examine their dynamics. Midnight Cowboy in 1969, Butch Cassidy and The Sundance Kid in 1969, Joe in 1970, Mean streets in 1973, Thunderbolt and Lightfoot in 1974, and Mikey and Nicky in 1976. All these films center around a dysfunctional friendship but they also feature men who live on the wrong side of the law.
