Doctor in the House is the American collective name for seven separate British and Australian television comedy series inspired by a series of cinema films, which in turn were based on and inspired by a series of books by Richard Gordon, about the misadventures of a group of medical students — and their later misadventures as doctors. The first five series, Doctor in the House, Doctor at Large, Doctor in Charge, Doctor at Sea and Doctor on the Go, were produced by London Weekend Television between 1969 and 1977. The sixth series, Doctor Down Under, which was filmed and based in Australia, was produced by Australia's Seven Network in 1979. The final series, Doctor at the Top, was produced by the British Broadcasting Corporation in 1991. The same theme music — "Bond Street Parade" by Alan Tew — was used for all of the "Doctor" television series, including the Australian series Doctor Down Under. Plot The plot revolved around the trials of medical students at St Swithin's hospital in London. Characters The television series would employ a set of characters completely different from the original book series (the film and radio series would use the characters from the books). The major protagonists were: Michael Upton (Barry Evans), an easy-going, serious and somewhat anxious son of a doctor who is essentially following in his father's footsteps. Duncan Waring (Robin Nedwell), Michael's best friend and roommate. He is just as bright as Upton, but far less serious in his studies, although he generally does well. After Barry Evans left the show, Nedwell returned as Waring to become the focus of the show. Paul Collier (George Layton), a less competent student and friend of Upton and Waring. Dick Stuart-Clark (Geoffrey Davies), a thirtyish student who deliberately fails his courses in order to take advantage of his late grandmother's will, which bequeathed him a large sum of money for each year he is in medical school. Stuart-Clark is the only character present throughout all seven series. Lawrence Bingham (Richard O'Sullivan), a brilliant, but arrogant and irritating doctor who believes he is the best of all possible doctors. He marries the equally obnoxious Dr. Mary Parsons (Helen Fraser) in the series Doctor in Charge. His need to continually impress her is the source of much comedy. The main antagonist is the well-respected and ill-tempered surgeon Professor (later Sir) Geoffrey Loftus (Ernest Clark). Most of the
