Gunsmoke wasn’t just a television show. It was a 20-year institution. Premiering on CBS in September 1955 and running through 1975, this Dodge City western holds the record as the longest-running primetime live-action drama in American TV history — 635 episodes across 20 seasons. At its peak, more than 30 million viewers tuned in each week to watch Marshal Matt Dillon keep order on the Kansas frontier. The show launched careers, defined a genre, and became the gold standard for serialized storytelling on television. Names like Arness, Blake, and Weaver became household fixtures. But that was half a century ago. The cast has aged, and most have passed on. Today, only one principal cast member is still alive. Here’s what happened to every major star of Gunsmoke — where they went after the cameras stopped rolling, and the legacies they left behind.

James Arness as Marshal Matt Dillon (Died 2011)
There’s no Gunsmoke without James Arness. He was Marshal Matt Dillon — appearing in all 635 episodes across the show’s full 20-season run. Standing 6’7″, the Minnesota-born actor brought a quiet, towering authority to the badge that no one else could’ve matched. Legend has it that John Wayne was offered the role first but turned it down and personally recommended Arness for the part.
Before Dodge City, Arness served in World War II at Anzio, where he was severely wounded. He carried shrapnel in his leg for the rest of his life. After the war, he hitchhiked to Hollywood and slowly built a career in B-movies and horror films, including The Thing from Another World (1951).
When Gunsmoke ended in 1975, Arness stayed close to the western genre. Between 1987 and 1994, he reprised Matt Dillon in five made-for-TV Gunsmoke movies. He published his autobiography in 2001 and lived a quiet, private life in Los Angeles. James Arness died on June 3, 2011, at the age of 88.
Amanda Blake as Miss Kitty Russell (Died 1989)
Amanda Blake brought Miss Kitty Russell to life for 19 of Gunsmoke‘s 20 seasons — one of the longest-running roles for a woman in TV history at the time. As the red-haired proprietor of the Long Branch Saloon, she gave Dodge City its heart and gave Matt Dillon someone worth coming home to. Her chemistry with Arness was one of the show’s defining elements.
Blake had been signed to MGM in the late 1940s, where the studio saw her as the next Greer Garson. But it was Gunsmoke that made her a star. The show’s demanding schedule meant she had little time for outside film work, though she did earn two Emmy nominations for the role.
After leaving the show, Blake moved into semi-retirement and dedicated herself to animal welfare. She founded the Arizona Animal Welfare League in 1971 — now the oldest and largest no-kill shelter in the state — and ran a successful cheetah breeding program. In 1977, she underwent surgery for oral cancer and became an advocate for the American Cancer Society. Amanda Blake died on August 16, 1989, from liver failure at the age of 60.
Milburn Stone as Doc Galen Adams (Died 1980)
Milburn Stone was the gruff, wise, and endlessly quotable Doc Adams — the man who patched up every gunshot wound and traded barbs with Miss Kitty over whiskey. He stayed with Gunsmoke for its entire run, missing only seven episodes in 1971 when he underwent open-heart surgery. The man literally had heart surgery and came back to work.
Stone’s career started decades before television even existed. He debuted on stage in 1919 in a Kansas tent show and spent the 1920s and 1930s as one half of a song-and-dance vaudeville act called Stone and Strain. By the late 1930s, he’d moved to Los Angeles and began picking up film roles. But it was Gunsmoke that defined him. He won a Primetime Emmy in 1968 for the role.
After the series ended, Stone largely retired from acting. He received a star on the Hollywood Walk of Fame and was posthumously inducted into the Western Performers Hall of Fame in 1981. Milburn Stone died of a heart attack on June 12, 1980, at the age of 75.
Dennis Weaver as Chester Goode (Died 2006)
Dennis Weaver’s Chester Goode was the comic relief Gunsmoke needed — the stiff-legged, coffee-brewing, loyal sidekick to Matt Dillon. The character’s distinctive limp and earnest personality made him one of the most beloved figures on the show. Weaver won an Emmy in 1959 for the role and stayed through Season 9 before departing in 1964 to pursue other opportunities.
And pursue them he did. Weaver had trained at the Actors Studio alongside Shelley Winters and carried serious dramatic chops. In 1970, he landed the title role in the NBC series McCloud, earning two more Emmy nominations. He worked steadily through the 1970s and 1980s in series like Stone and Buck James, and also released several music albums between 1959 and 1984.
From 1973 to 1975, Weaver served as president of the Screen Actors Guild. In his later years, he became a passionate environmental activist, promoting alternative fuels and sustainable living. He also earned a star on the Hollywood Walk of Fame. Dennis Weaver died on February 24, 2006, from complications of prostate cancer. He was 81.
Ken Curtis as Festus Haggen (Died 1991)
When Dennis Weaver left Gunsmoke in 1964, the show needed a new sidekick. Enter Ken Curtis as Festus Haggen — the scruffy, plain-spoken, fiercely loyal deputy who couldn’t spell but could track a man across bare rock. Curtis joined in Season 9 and held the role for 11 years and 304 episodes, making Festus the longest-serving deputy in the show’s history.
What most fans don’t know is that Curtis was also a gifted singer. Before acting, he performed with the Sons of the Pioneers and the Tommy Dorsey Orchestra. He even had a brief solo recording career. But it was Festus that audiences loved him for.
After Gunsmoke ended, Curtis worked sporadically in television. His final acting credit was the 1991 TV movie Conagher. He was inducted into the Western Performers Hall of Fame in 1981. Ken Curtis died in his sleep on April 28, 1991, of a heart attack. He was 74.
Buck Taylor as Newly O’Brien (Alive — Last Surviving Main Cast Member)
Here he is. The last one standing. Buck Taylor — born Walter Clarence Taylor III on May 13, 1938, in Hollywood, California — is the sole surviving principal cast member of Gunsmoke. At 88 years old in 2026, he’s the living link to a show that shaped American television.
Taylor joined Gunsmoke in 1967 as Newly O’Brien, the town’s gunsmith-turned-deputy. He appeared in 196 episodes through the show’s final season in 1975. The son of character actor Dub Taylor, Buck grew up around movie sets and carried an easygoing authenticity that fit Gunsmoke like a well-worn saddle.
After the series ended, Taylor continued working in westerns and guest-starring on television shows through the 1980s and 1990s. He appeared in several of the Gunsmoke reunion movies alongside James Arness. But his second act has been just as remarkable — Buck Taylor became a respected Western painter and sculptor, selling his artwork at galleries and rodeo events across the country. He’s a regular at fan conventions and western heritage festivals, where he remains one of the most beloved figures in the genre. Buck Taylor is living proof that the spirit of Gunsmoke hasn’t faded.
Burt Reynolds as Quint Asper (Died 2018)
Of all the actors who passed through Dodge City, Burt Reynolds had the biggest career after leaving. He played Quint Asper, the town’s half-Comanche blacksmith, from 1962 to 1965. It was a relatively short stint — just three seasons — but it put Reynolds on the map and set the stage for one of the most iconic careers in Hollywood history.
After Gunsmoke, Reynolds tore through the 1970s like a freight train. Deliverance, The Longest Yard, Smokey and the Bandit, Hooper — he was the number-one box office star in the world for five consecutive years, from 1978 to 1982. No one else has matched that streak. He earned Golden Globe nominations and became as famous for his charm and mustache as for his acting.
His career dipped in the late 1980s, but he roared back in 1997 with Boogie Nights, earning an Academy Award nomination. Reynolds continued working until the very end. He died of a heart attack on September 6, 2018, at the age of 82. Two posthumous films, An Innocent Kiss (2019) and Defining Moments (2020), served as his final screen appearances.
Glenn Strange as Sam Noonan (Died 1973)
Glenn Strange was the quiet anchor of the Long Branch Saloon. As bartender Sam Noonan, he didn’t get the big speeches or the dramatic showdowns. He poured drinks, wiped the bar, and kept things running in the background. But that steady, reliable presence made him a fan favorite across 211 episodes from 1962 to 1973.
Before Gunsmoke, Strange had one of the most unusual resumes in Hollywood. He’d been a rodeo rider, a radio musician, and — most famously — he played Frankenstein’s Monster in three Universal horror films: House of Frankenstein (1944), House of Dracula (1945), and Abbott and Costello Meet Frankenstein (1948). Not many actors can claim they went from playing a reanimated corpse to pouring whiskey on a western set.
Sadly, Strange passed away during the show’s final season. Glenn Strange died on September 20, 1973, from lung cancer at the age of 74. His last episodes aired posthumously, and the cast and crew paid tribute to him throughout the remainder of the series.
