From Taste of Cinema: For this list, the usual suspects had to be rounded up: The Duke, Lee Marvin, Sly Stallone, The Governator, Bruce Willis, Walter Hill, Clint Eastwood, and all the rest of these awesome b*****ds.
I decided to make the list diverse. There's a western in here, a war movie, a buddy-cop action movie, a one-man army movie, even a badass historical epic. It needed to be filled with a few films that even pretentious film buffs could enjoy. They wouldn't feel guilty watching an excessively violent film because the dialog would be great and/or the cinematography would be stunning.
The list needed a few films with awesome one-liners, but it also needed some grit. It couldn't be all schlocky, there had to be some poignancy too. Most of all, the list needed to be filled with films about male friendship, the close bond that men can have amidst the fire and brimstone.
