Schooled by Master Po (a.k.a. Sug)

Sug's comment was too good NOT to post as it's own entry...

"They're Gangster Tough which is its own breed and his hair is downright funky.

See, grasshopper, there are different types of tough:

Gangster Tough: DeNiro, Pacino, Samuel L. Jackson

Cop Tough: (Similar but a little different) Bruce Willis, Charles Bronson, James Garner

Crazy Tough: Mel Gibson (Lethal Weapon, Mad Max), Kurt Russell ("Escape from..." franchise)

Cowboy Tough: Clint Eastwood, Clint Walker, John Wayne, Christian Bale,

Soldier Tough: (Similar to cowboy) Lee Marvin, Kirk Douglas, Russell Crowe

Unexpected Tough / Reluctant Hero (rises to the challenge): Harrison Ford, Viggo Mortensen, Hugh Jackman, Jackie Chan, Will Smith

Cartoon Tough: Arnold Schwarzenegger, Sly Stallone

Stately / Biblical Tough: Charleton Heston, Richard Burton,

There are others - I could go on and on like Spies (toys and slick martial arts): Jet Li, Daniel Craig,

Now you'd never see Chuck Heston playing Snake Plissken (Russell) and you'd never see DeNiro as the Man With No Name in Pale Rider but they are all Tough Guys.

Here endeth the lesson. "
