Gunsmoke was more than a television series — for millions of Americans, it was a weekly tradition. Now, fans are mourning the loss of one of the actors who helped make Dodge City feel like home.
Roger Ewing, the tall, gentle-voiced actor best known for playing deputy marshal Thad Greenwood in the 1960s, has died at 83. His family confirmed that he passed away on December 18 at his longtime residence in Morro Bay, California, according to The Hollywood Reporter.
Standing 6-foot-4 with a rugged, blond appearance, Ewing first appeared on Gunsmoke in February 1965 in the episode “Song for Dying,” originally playing a character named Ben Lukens. A few months later, he officially joined the cast as Thad Greenwood, debuting in season 11 when he was just 23 years old. He quickly became a familiar and reassuring presence on the long-running CBS western.
Thad was introduced as the son of an aging Oklahoma sheriff, portrayed by Paul Fix, who comes to Dodge City seeking justice for his father’s fatal heart attack. Although his legal authority doesn’t extend to Dodge, the criminals are ultimately caught or killed, leading Marshal Matt Dillon (James Arness) to invite Thad to remain as a deputy.
Ewing later explained that Thad naturally blended into the show’s core group. With no family left, Thad was essentially taken in by Matt, Kitty, Doc, and Festus. He was the extra set of hands — always there when needed.
Ewing appeared in 50 episodes through 1967, during a period when the show’s ratings dipped. As viewership rebounded, his role was gradually reduced and eventually written out.
Born Roger Lawrence Ewing in Los Angeles on January 12, 1942, he had been a Gunsmoke fan long before joining the cast. As a teenager, he even played Chester in a parody of the show. After a year of college and work as a lifeguard, he turned to acting, landing his first uncredited film role in Ensign Pulver (1964).
Television roles soon followed, including appearances on Bewitched, Rawhide, The Bing Crosby Show, and The Baileys of Balboa, as well as Frank Sinatra’s film None But the Brave. Ewing often joked that he was typecast as awkward, tall characters.
When Burt Reynolds left Gunsmoke, producers sought a younger presence and cast Ewing as Clayton Thaddeus Greenwood. At the time, tensions between CBS and James Arness led to contingency plans that ultimately proved unnecessary. Once the situation stabilized, Thad was replaced by Buck Taylor’s Newly O’Brien.
Ewing narrowly missed a major film breakthrough when he was reportedly considered for Midnight Cowboy, a role that ultimately went to Jon Voight. He also appeared on The Dating Game, though was not chosen by contestant Lindsay Wagner.
After Gunsmoke, Ewing continued acting in television and films such as Smith! and Play It as It Lays, before leaving the industry entirely. He later reinvented himself as a photographer, traveled widely, and became involved in local politics, even running for city council in Morro Bay in 2003.
To Gunsmoke fans, Roger Ewing will always be remembered as Thad — the reliable young deputy who didn’t need to stand out to matter. For generations of viewers, he remains part of what made Dodge City feel like home.
