Hollywood He-Men

The list of actors who could replace aging Hollywood he-men, such as eligible-for-retirement stars Sly Stallone and Clint Eastwood, is short. Pass the popcorn as we look at their careers, their movies and the guys we think could fill their shoes.

Liam Neeson

Liam Neeson, 58, is the latest in a long list of graying actors starring in action films. His new movie "Unknown" opened Feb. 18.

Harrison Ford

Harrison Ford

He may be best known for the "Indiana Jones" movies, but Ford has been holding his own in action-packed flicks for decades. "Star Wars" fans will remember him as Han Solo in the late '70s and early '80s. And he's still going strong. Ford stars in the Jon Favreau- directed "Cowboys and Aliens" scheduled for release this year.

Robert De Niro

Robert De Niro

He may be best known for his iconic mobster roles, but like Harrison Ford, Robert De Niro has a résumé that reaches back decades, with some of his most iconic action-packed movies first appearing in the late '70s and early '80s. But he hasn't yet reached his limit and will star in the suspense-thriller "Limitless" next month.

Clint Eastwood

Though he's also a respected film director, Clint Eastwood, the most senior actor in this slideshow, has been acting since the 1950s and made his mark in Western and action films. Here are just a few of his most famous action roles.
Sylvester Stallone

Sylvester Stallone

Sly Stallone has done little memorable acting outside of action films, and for good reason: His action movies are iconic. And he's still doing them. "The Expendables" was released last year, and its sequel is due in 2012. Here are some of his most famous roles.
Arnold Schwarzenegger

Before he ventured into the world of politics as governor of California, Arnold Schwarzenegger was a champion bodybuilder-turned-action-movie icon.

Bruce Willis

Bruce Willis

It's rare for Bruce Willis to star in a movie in which he's not wielding a gun. But he's so darned good at it, it's OK with us. He, too, is a veteran of action movies -- he's also in both the "Expendables" films -- and first gained notoriety for the genre in 1988's "Die Hard" as Officer John McClane. Here's a look at some of his other memorable roles.

Jean-Claude Van Damme

Jean-Claude Van Damme
