Actor/director Robert Redford dismissed the idea of a career in politics after witnessing first-hand how his celebrity would prove too distracting for him to be taken seriously.
The All The President's Men star became disillusioned when he followed Democrat candidate George MCGovern's U.S. presidential campaign in 1972 - and he soon realised he could attract a larger crowd simply because he was a Hollywood star.
Redford tells Playboy magazine, "Every film about politics I've made makes the point that politics compromises you. Your hands are tied, and I would never want to be in that position.
"I lost all interest in going into politics around the time the Watergate break-in occurred. I was promoting The Candidate, and I did a whistle-stop train tour with George MCGovern and some other candidates.
"I wanted to make the point that I could draw more people just by standing on the back of the train. And that's what happened. They would draw 300 or 400 people, then I would go out and get 3,000 or 4,000.
"I would tell the crowds, 'Thank you all for coming. My fellow Americans, I just want you to know I have absolutely nothing important to say.' And they would cheer."
