Obi Wan and Luke, Kirk and Spock, Harold and Kumar, Wayne and Garth, Butch Cassidy and The Sundance Kid. The list of classic bromances goes on and on—and this summer may be the bromanciest ever. In fact, we spotted a dozen films capitalizing on the (potentially cheesy) male-bonding movie format. Each exemplifies a different kind of mano-a-mano relationship: classic frat-boy bromance, dynamic-duo bromance, whoa-this-is-actually-a romance bromance . . . you get the idea. We've organized the list below chronologically by release date because, yeah, we love ya, man.
