(CNN) -- Though Sir David Frost doesn't see his 1977 interviews with former President Richard Nixon as "an intellectual 'Rocky' " -- in the words of "Frost/Nixon" playwright and screenwriter Peter Morgan -- he does agree that the sessions had their "adversarial" moments. David Frost's interviews of Richard Nixon were some of the most watched programs of their time. Particularly, he told CNN, when the topic turned to the Watergate scandal. "By halfway through the second day [of the interviews], we had got to the point that we had hoped to get to," he said. "And then it was a point of going further and trying to get more than we had really expected."
