Sir David Frost, the veteran broadcaster and writer, has died of a suspected heart attack while traveling aboard the Queen Elizabeth where he was delivering a speech on Saturday night, according to the BBC. He was 74. Frost’s long career spanned journalism, heavy-hitting TV interviews, game show hosting and comedy writing. He notably conducted a series of televised sit-downs with former president Richard Nixon in 1977. They were the basis of a 2006 play by Peter Morgan, which was then adapted as Ron Howard’s 2008 film, Frost/Nixon. Michael Sheen played Frost and the film was nominated for five Oscars. In the early 1960s, Frost hosted the satirical program That Was The Week That Was on the BBC and also featured on an American version for NBC from 1964-1965. In 1968, he helped launch London Weekend Television, which is now part of ITV. His other on-air TV credits included The Frost Report, The David Frost Show, Through The Keyhole, Breakfast With Frost and, more recently, Frost Over The World for Al Jazeera English. A statement released by his family today said details of a memorial service will be announced in due course.
