Walter Bruce Willis was born on March 19, 1955, in the town of Idar-Oberstein, West Germany. His father, David Willis, was an American soldier. His mother, Marlene, was German, born in Kassel. Willis is the oldest of four children with a sister named Florence and two brothers, Robert (who is deceased) and David.

In 1988, Willis and then-wife Demi Moore campaigned for Democratic Massachusetts Governor Michael Dukakis's Presidential bid. Four years later, he supported President George H. W. Bush for reelection and was an outspoken critic of Bill Clinton. However, in 1996, he declined to endorse Clinton's Republican opponent Bob Dole, because Dole had criticized Demi Moore for her role in the film Striptease. Willis was an invited speaker at the 2000 Republican National Convention, and supported George W. Bush that year. He did not make any contributions or public endorsements in the 2008 presidential campaign. In several June 2007 interviews, he declared that he maintains some Republican ideologies.  In 2006, he said that the United States should intervene more into Colombia, in order to end the drug trafficking. In several interviews Willis has said that he supports large salaries for teachers and police officers, and said he is disappointed in the United States foster care system as well as treatment of Native Americans. Willis also stated that he is a supporter of gun rights, stating, "Everyone has a right to bear arms. If you take guns away from legal gun owners, then the only people who have guns are the bad guys."  In February 2006, Willis appeared in Manhattan to talk about his film 16 Blocks with reporters. One reporter attempted to ask Willis about his opinion on the current government, but was interrupted by Willis in mid-sentence: "I'm sick of answering this fucking question. I'm a Republican only as far as I want a smaller government, I want less government intrusion. I want them to stop shitting on my money and your money and tax dollars that we give 50 percent of every year. I want them to be fiscally responsible and I want these goddamn lobbyists out of Washington. Do that and I'll say I'm a Republican. I hate the government, OK? I'm apolitical. Write that down. I'm not a Republican."  Willis's name was in an advertisement in the Los Angeles Times on August 17, 2006, that condemned Hamas and Hezbollah and supported Israel in the 2006 Israel-Lebanon war.
