Richard O’Sullivan, who has died at the age of 82, began his acting career by accident. As a boy, he returned from a family holiday in Ireland with a strong accent, prompting his parents to send him to the Corona Theatre School in London to help him sound more “British.” This story of an accidental actor reflected O’Sullivan’s lifelong image: a down-to-earth, cheeky, and lovable character, the kind of person who would never have considered drama school for the sake of acting. His early career was fast-paced—he filmed his first feature at age eight as an extra in The Yellow Balloon, and by 1954, he was already playing the lead in The Stranger’s Hand. He later appeared as the younger brother of Audrey Hepburn in The Nun’s Story (1959) and Elizabeth Taylor in Cleopatra (1963). However, transitioning from child star to adult actor is notoriously difficult, especially when one is already famous as a child. During this awkward period in the early 1960s, he appeared in two films starring Cliff Richard, The Young Ones and Wonderful Life, where his wholesome, boyish charm hinted at the comic actor he would become. O’Sullivan’s first adult leading role came in 1972 in Alcock and Gander, a comedy co-created by Johnnie Mortimer and Brian Cooke. The show Man About the House, which followed in 1973, became one of his most iconic roles. He played Robin Tripp, a trainee chef who moves into a flat shared by two women—Paula Wilcox and Sally Thomsett—after a party. The premise was simple but groundbreaking: the women pretend Robin is gay to get past their landlord, creating a sitcom that blended innocence with a subtle challenge to traditional gender roles. Robin’s character was a new kind of masculinity—handsome, boyish, and unthreatening, yet constantly flirtatious and charming. His ability to play along with the charade while never fully suppressing his natural charm made him a beloved figure in British television. The spin-off series Robin’s Nest continued O’Sullivan’s character’s journey into adulthood, where he was in a relationship with Vicky Nicholls, played by Tessa Wyatt. This was radical for its time, as it depicted the first unmarried cohabiting couple in a British sitcom. O’Sullivan’s natural warmth and charm helped make the show feel both progressive and comforting. Off-screen, he was also in a relationship with Wyatt, and had previously dated Thomsett during Man About the House. These real-life connections were of little concern to his fans, who were more interested in his on-screen persona—charming, affable, and effortlessly likable. He even wrote cookbooks and appeared in advertisements for British Gas, reinforcing his image as the “new man” who could cook, laugh at himself, and still be the center of attention. O’Sullivan continued acting well into the 1990s, taking on smaller roles even after his leading man years had passed. However, he struggled with poor health in the late 1990s, suffering a stroke in 2003. Despite this, he remained a symbol of the 1970s domestic ideal—rascally but not roguish, attractive but not macho. He helped bridge the gap between the grumpy, often one-dimensional male characters of older sitcoms and the more nuanced, relatable men of the future. Richard O’Sullivan left behind a legacy of charm, adaptability, and a reassuring belief that, no matter where the world was headed, it would probably be fine.
