Morro Bay, California — Roger Ewing, recognized predominantly for his role as deputy marshal Thad Greenwood in the iconic television western “Gunsmoke,” has passed away. Ewing died on December 18, 2025, at the age of 83 in his home in Morro Bay, California, according to family sources.
Ewing’s portrayal of Thad Greenwood, whom he joined in 1965, became a defining role in his career, showcasing his robust 6-foot-4 stature and commanding presence on the CBS series. He appeared first as a character named Ben Lukens in February 1965 before reappearing as Greenwood later that same year.
Reflecting on his character’s integration into the “Gunsmoke” family, Ewing noted that the core characters, such as Matt, Kitty, Doc, and Festus, all adopted Thad after his family had passed away. He described Greenwood as a utility character, always there to lend a hand wherever needed, seamlessly fitting into the bustling environment of Dodge City.
During his tenure on the show from 1965 to 1967, Ewing starred in fifty episodes alongside the likes of James Arness, playing Marshal Matt Dillon, and other notable co-stars including Amanda Blake, Milburn Stone, and Ken Curtis as Festus. His time on the series bridged a pivotal transition between Burt Reynolds’ departure and Buck Taylor’s arrival as Newly O’Brien.
Born in Los Angeles on January 12, 1942, Ewing’s journey into the world of acting began with his on-screen debut in the 1964 film “Ensign Pulver.” Before his significant break in “Gunsmoke,” he appeared in other TV shows such as “Bewitched,” “The Bing Crosby Show,” and “Rawhide,” as well as in the Frank Sinatra film “None But the Brave.”
Post “Gunsmoke,” Ewing continued his acting career with roles in television series including “The Mothers-in-Law” and “Death Valley Days,” and films like “Smith!” (1969) starring Glenn Ford, and “Play It as It Lays” (1972) featuring Tuesday Weld and Anthony Perkins.
After a fruitful career in film and television, Ewing decided to leave acting to pursue photography, a long-time passion. This new career path took him across Europe, Russia, Mexico, and the South Pacific. Through photography, Ewing was able to explore a different aspect of his creative inclinations, engaging with diverse cultures and landscapes far removed from his Hollywood beginnings.
Later in life, Ewing also turned his focus towards local politics in Morro Bay. Running for a city council seat in 2003, he demonstrated a commitment to his community and an ongoing interest in public service, indicating his dedication to issues beyond the entertainment industry.
“Gunsmoke” remains a seminal part of American television history, setting a standard for television westerns and serving as a springboard for many acting careers. Ewing’s role as Thad Greenwood left an indelible mark on the series and continued to bring joy to viewers in syndication, introducing new generations to his work.
Ewing’s shift from acting to photography was a bold move that highlighted his desire for creative exploration and freedom—a testament to his character.
