"Parkinson" was a flagship of the BBC's prime time schedule, attracting top names before the chat show circuit was part of the promotional mill. Parkinson interviewed Marlon Brando, he was able to interview wartime variety stars while attracting up-and-coming comedians such as Billy Connolly, and was not afraid to allow an interviewee time to be himself, sometimes, as with Fred Astaire, Orson Welles, Sir Alec Guinness, Sir Paul McCartney, Muhammad Ali, George Michael, Madonna, John Cleese and Mel Gibson, devoting an entire programme to a guest who was considered especially noteworthy.
