The Films of Sam Peckinpah.

This macho action film starring Gerard Butler and Morgan Freeman is a vigilante fantasy about terrorists and turncoats invading the United States. It's a popular genre, but critic David Edelstein says he's tired of the American addiction to these tropes.

With his latest film, director Quentin Tarantino was inspired both by spaghetti Westerns and the drama of slavery and the Civil War. The movie is extremely violent — but, says Tarantino, "What happened during slavery times is a thousand times worse. ... If you can't take it, you can't take it."

Director Arthur Penn changed the face of cinema with his film, Bonnie and Clyde. The graphic realism of the last scenes have influenced television and movies since the film's release in 1967.
