Peter Graves died of a heart attack at his Los Angeles home today. He was an actor who seemed to do a little bit of everything, and where you know him from might depend on your age.

He was team leader Jim Phelps on 'Mission: Impossible' in the '60s and also had a memorable role as the pilot Captain Oveur in the first two 'Airplane' movies in the '80s. He was also the host of A&E's 'Biography' for ten years and appeared in several commercials ("I'm Peter Graves..."). You might even know him from voice work he did on 'American Dad.' He had a recurring role on '7th Heaven' and guest roles on 'Cold Case,' 'House,' 'Diagnosis: Murder,' 'The Love Boat,' 'Fantasy Island,' and other shows.

Graves wasn't happy about Phelps being the bad guy in the big-screen 'Mission: Impossible' movie but was actually going to film a cameo in the fourth film in the franchise.

Graves was the brother of another TV icon, 'Gunsmoke's' James Arness. After the jump, the opening to 'Mission: Impossible.'
