Today, we're celebrating the 57th birthday of actor Bruce Willis. The actor has made a name for himself as an action movie star, but he has been acting for quite some time. He made his first appearance in a feature film in 1980's The First Deadly Sin, but it wasn't until his starring role in 1988's Die Hard that he truly burst onto the Hollywood scene. He has reprised the role on three subsequent occasions, and there is supposedly a fifth Die Hard film in the works (it is currently slated for a 2013 release). In between those films, Willis has also starred in big-time flicks like 1994's Pulp Fiction, 1995's Twelve Monkeys, 1998's Armageddon, 1999's The Sixth Sense and 2005's Sin City. Often portrayed as the tough guy with a witty comment on the tip of his tongue, Willis has become one of the most popular action stars in Hollywood. So, to celebrate his birthday, I've listed my five favorite of Bruce Willis's performances, and I've supplied videos where possible. Once again, happy birthday, Bruce!
