Robert Redford took an instant dislike to shamed U.S. leader Richard Nixon when he met the future president at the age of 13.

The actor, who famously played one of the journalists investigating the Watergate scandal in 1976 movie All the President's Men, was just a teenager when he was handed an athletics award by the politician in 1950.

Redford admits he had no idea who Nixon was at the time, but he instantly disliked him.

Speaking at a Los Angeles screening of his latest movie, The Company You Keep, he told reporters, "I didn't know who he was. He was just a guy in a suit. When Nixon handed me the award and shook my hand, it was just a vibe. I thought, 'I don't like this guy.'"

The explosive Watergate scandal, when burglars employed by the ruling Republican Party tried to bug the Democratic National Committee Hq, led to President Nixon's resignation in 1974. Redford has re-visited the story in a new documentary called All the President's Men Revisited, which will air in the U.S. in April (13).
