A real- life version of the story: starring Jackie Gleason!
Seeing this movie reminded me how Jackie Gleason found himself in EXACTLY the same position Cary Grant was in! By the mid-1950s Gleason was on top as a TV star, but he had been informally separated from his wife Genevieve Halford Gleason for several years. In the meantime, he had fallen in love with Marilyn Taylor, a featured dancer on his CBS variety show. Her sister June was the show's choreographer (remember The June Taylor Dancers?). However, Jackie had an accident before the TV cameras: millions watched as he slipped on the floor and broke his leg during a sketch. He was rushed to the hospital. Genevieve came to the hospital to find Marilyn at her husband's bedside! A nasty scene ensued, and she soon filed for a formal separation, more or less exposing the affair. Jackie couldn't get a divorce as Gen cited their Catholicism as a deterrent, and Marilyn gave up, marrying someone else some time later.
Cut to 1974- by then Jackie had finally divorced Gen and married another woman, but he was unhappy. Meanwhile, Marilyn Taylor was a widow with a young son. Thanks to sister June, the two reunited, and he soon left his wife for Marilyn. They married in 1975, and stayed together until his death in 1987. The parallels between this true story and "In Name Only" are QUITE interesting!
