Wexler played Clem Scobie, a war hero, in the 1955 episode "The Homeliest Man in Nevada" on the western anthology series, "Death Valley Days." In the story line, Clem's unattractive looks at first discourage Mona Sherman (Patricia Joiner), who came to Nevada from Emporia, Kansas, from accepting his romantic gestures. When Clem is badly burned in a mining explosion, however, Mona rushes to his side and confesses her love for him. By the 1970s, Wexler had begun to limit the frequency of his acting on television and in films, possibly due to his declining health. He still continued to perform in nearly a dozen other television series during that decade, including "Get Smart", "Mod Squad", "Switch", "Charlie's Angels", "Police Woman", and "The Amazing Spider Man". Wexler's final role was in a 1979 episode of "Stockard Channing in Just Friends", one titled "Lost Weekend", which was broadcast in April that year, just seven months before his death. Wexler was married three times, the first time to actress and fellow Oregon native Susan Fox McAndie. Their wedding was on November 29, 1952, in North Hollywood, California. She and Paul had one child together, a son named Alan Ross Wexler, who was born in 1955 but later raised by relatives in Oregon after Susan died in a car accident in 1958. Paul subsequently married another actress, Carole Minor; however, they divorced. He and his third wife, Marcella Wexler, remained together until his death. Outside of acting, Wexler invested in several business ventures, including a partnership "around 1960" in "Dino's Lodge", a Dean Martin-themed restaurant. Wexler was also a car and racing enthusiast and was one of the early presidents of the Mini Owners of America, a club devoted to the history, collection, and recreational driving of the classic "Mini-Coopers" that were produced by the British Motor Corporation between 1961 and 1971. In his free time too, he supported and promoted the interests of the film industry, especially projects developed outside the mainstream studio system. He served, for example, as president of the Independent Film Producers of America. Wexler died of leukemia in Los Angeles, California, in November 1979. His gravesite is located in the "Canaan" section of Mount Sinai Memorial Park in Los Angeles.
