Roger Ewing (born January 12, 1942) is a former actor originally from Los Angeles, California. He is best remembered for his characterization of part-time deputy marshal Clayton Thaddeus "Thad" Greenwood in thirty-six episodes (October 2, 1965 - September 25, 1967) of the long-running CBS western television series Gunsmoke with James Arness. Among Ewing's last Gunsmoke appearances were on episodes entitled "The Prodigal", "Nitro" (Parts 1 and 2), "Ladies from St. Louis" and "Mistaken Identity". Before he was cast as Thad, Ewing appeared on Gunsmoke once in the role of Ben Lukens in the episode "Song for Dying", which aired on February 13, 1965. Ewing's first television appearance was in 1964 as Marvin Grogan on ABC's sitcom Bewitched (Elizabeth Montgomery) in the episode entitled "The Girl Reporter". He also appeared that season as Eddie Fox in the episode "The Christmas Show" of ABC's short-lived The Bing Crosby Show, starring Bing Crosby and Beverly Garland, and in a third sitcom as well in the role of Norman in the episode entitled "Look Who's a Sailor" on CBS's short-lived The Baileys of Balboa. In 1965, Ewing, at twenty-three, appeared as Private Swensholm in the World War II film None But the Brave starring Frank Sinatra and Clint Walker. That same year, he appeared as Billy Wallace in the episode "The Calf Women" of CBS's western Rawhide starring Eric Fleming and Clint Eastwood. After his Gunsmoke role ended, Ewing appeared in two films: as Donald Maxwell in the western production Smith! starring Glenn Ford (1969) and as Nelson in Play It As It Lays, a psychiatric drama starring Tuesday Weld and Anthony Perkins (1972). He also made a guest starring appearance on the sitcom The Mothers-in-Law as a wealthy former boyfriend of the character played by Deborah Walley.
Ewing's Gunsmoke character was superseded by that of Newly O'Brien, portrayed by Buck Taylor, son of character actor Dub Taylor. After his acting career ended, Ewing returned to his previous work as a photographer.
It would have been more logical if silent pictures had grown out of the talkies instead of the other way around.
After Roger Ewing decided to call it quits for his acting career he pursued his other passion in the field of photography.
