Actor Peter Graves has passed away at the age of 83 after suffering a heart attack in Los Angeles.
Graves was best known for his role as Jim Phelps, ringleader of the superspies in the TV series Mission: Impossible. His supercool persona was a model for many smooth-yet-tough-as-nails television characters that followed, and he hysterically lampooned it as Captain Oveur in the classic comedy Airplane! ("We have clearance, Clarence."). In his later years, Graves became the host and narrator for A&E;'s popular Biography series.
Graves appeared in several films, including classics from Billy Wilder and John Ford and more modern fare such as Addams Family Values and Men in Black II. He also was the centerpiece of a popular Geico commercial.
