Matthew Macfadyen has said he prepared for his role as John Burt in Frost/Nixon by meeting the man himself.

The actor plays David Frost's producer at the time of his historic interviews with former US President Richard Nixon, and said the meeting was invaluable for learning about the times.

"We met in London before I came over here to shoot. I don't know why I did, I wasn't trying to do a slaveless impersonation of him because he's not in the public eye in the way that David Frost is and Richard Nixon was. But I had a sort of check list that I sort of picked his brains about what the field was like at the time, it was useful," he said.
