From The NYT:

Peter Graves, the cool spymaster of television’s “Mission Impossible” and the dignified host of the “Biography” series, who successfully spoofed his own gravitas in the “Airplane” movie farces, died Sunday. He was 83.

He died of a heart attack at his home in Pacific Palisades, Calif., said Fred Barman, his business manager.

It was a testament to Mr. Graves’s earnest, unhammy ability to make fun of himself that after decades of playing square he-men and straitlaced authority figures, he was perhaps best known to younger audiences for a deadpan line in “Airplane!” (“Joey, do you like movies about gladiators?”) and one from a memorable Geico car insurance commercial (“I was one lucky woman”).
