time now for the sunday spotlight. If you're one of the movie goers who drove the butler to the top of the box office this weekend, you saw a remarkable story inspired by eugene allen. Which inspired us to find bill hamilton. He retired after 55 years in the white house serving 11 presidents. We have his story. We have no tolerance for politics at the white house. You hear nothing. You see nothing. They swore him to a secret code. Reporter: In the new movie the butler, hollywood highlights the life of eugene allen, one of the men who served the first family behind the scenes. When the president comes in, it doesn't matter if they're democrat or republican, you're there for the president. Reporter: Bill hamilton, while not featured in the film, he has been here since he was 20, retiring at age 75. An incredible half century at the home of the most powerful man in the country. A part of history. Nixon retined from the presidency, that was a hard time and I didn't think I would see that. When the president was assassinated. And we get the first black president, I didn't think that would happen in my life. Reporter: Hamilton served every president from eisenhower to obama. Working as a head storekeeper, part of the resident staff. What are some of the items popular among presidents over the years? Well, clinton loved beef and hamburger and stuff. 41 didn't like broccoli. It could not be served at the white house. And mrs. Reagan, she loved calf liver. Reporter: Small moment, and then there were significant ones too. The march on washington, martin luther king. They say you can't go out there, you're going to lose your job. You won't lose your job. I went out and listened to his speech. It was really, really thrilling. Reporter: One of hamilton's proudest moments came during the most painful period in american history. What was is like being a black man in the white house during the civil rights movement? It was hard. They were promoting other people and not the blacks. Reporter: So he gave an ultimatum on behalf of the black butler staff. They wanted more pay or they wouldn't work at a state dinner. We're not going to work the state dinner. This was the only way we were going to get a raise. Two days later, we got the raise. Reporter: Oprah winfrey was awed by their courage. You think of a butler, you think of a servant bowing down. The grace and nobility that it took to do that. To hold your head up every day. I have a greater sense of pride for those men in that time. Reporter: A time hamilton says he'll never forget. Five decades of white house from the obamas. Is there anything that you feel you're going to regret that will happen at the white house that you wish you were still there for? If miss clinton was to win. First female president. Reporter: What do you think of bill clinton being first lady? He's going to be telling jokes. How he's going to hold the senate womens luncheon. Reporter: For "this week," abc, washington. What a record of service. Now we honor our fellow american who serve and sacrifice. This week, the pentagon released killed in afghanistan. That's all for us today. Thanks for sharing part of your sunday with us. Check out world news with david muir tonight. I'll see you tomorrow on "gma." Muir tonight. I'll see you tomorrow on "gma."
