James Arness, the tall, iconic actor best known for playing Marshal Matt Dillon on the long-running television series "Gunsmoke," has died. He was 88.

The Los Angeles Times reports the actor died Friday of natural causes.
According to the biography on his website, Arness was born on May 26, 1923, in Minneapolis. His first job in show business was as a radio announcer in Minnesota in 1945.
He moved to Los Angeles and got a part in the 1947 movie "The Farmer's Daughter" starring Loretta Young. He played The Thing in the 1951 science fiction classic, "The Thing from Another World."
After befriending John Wayne and acting in films for his production company, Wayne suggested the 6' 7" actor play Marshal Matt Dillon in the upcoming television series "Gunsmoke." Arness won the part and played Dillon for 20 years, becoming a TV icon in the process.
He made few films during the 20-year "Gunsmoke" run. (There were 635 episodes produced in the series over its long tenure.) Arness was nominated for three Emmys over those 20 years and reprised his role as Dillon in made-for-TV "Gunsmoke" movies in the 1980s and 1990s. He also starred in mini-series "How the West was Won" in the late 1970s.
Arness was a World War II veteran. According to the LA Times, he was drafted in 1943 while attending Beloit College in Wisconsin and assigned to the 3rd Infantry Division, taking part in the landing at Anzio, Italy, in 1944.
