(10:00 a.m. EDT) -- Revered British broadcaster Sir David Frost has died of a suspected heart attack at the age of 74 while onboard Cunard's Queen Elizabeth.
The BBC reported that Frost had been giving a speech on the ship Saturday night as a guest lecturer, and cited a statement from Frost's family.
Peter Shanks, Cunard Line's Managing Director, expressed sadness over Frost's death, saying: "Sir David Frost was a remarkable journalist and broadcaster. Cunard had a proud association with him over many years. On behalf of us all at Cunard Line I would like to extend our deepest sympathy to his wife, family and friends."
Many other notable figures have joined in a chorus of condolences and tributes, including British Prime Minister David Cameron as well as colleagues with whom Frost worked during his more than 50-year career.
Although he worked with contemporaries such as John Cleese on satirical and sketch comedies early in his career, Frost is probably best known for a series of interviews he conducted with former President Richard Nixon. The interviews were eventually made into a 2008 film, "Frost/Nixon," in which Frost was portrayed by Michael Sheen and Nixon was played by Frank Langella.
Queen Elizabeth left Southampton yesterday, August 31, bound for Lisbon, the first call on a 10-night Mediterranean cruise to Civitavecchia (Rome).
