The show was a spin-off of Jake and the Fatman. Dr. Mark Sloan made his first appearance in Jake and the Fatman's episode 4.19, "It Never Entered My Mind". Afterwards, three TV movies aired prior to the start of the series.
Based on the popular 1980spolice drama of the same name, the regular series debuted on CBS on October 29th, 1993, and became a rapid success, airing in many countries around the world. Almost canceled at the end of the second season, it returned as a midseason replacement in the third season. 178 episodes were made and aired in the show's eight seasons on the CBS network in the United States and two more TV movies aired after the series' cancellation on May 11th, 2001. Since 1997, the popular show used to air in reruns on ABC Family (formerly The Family Channel), and today, the show is currently airing on both ION Television (formerly i: Independent Television and PAX TV) and Hallmark Channel.
Dr. Mark Sloan (Dick Van Dyke), Chief of Internal Medicine at Community General Hospital. Son of a cop and father of another, in whose cases he often got involved. He has a great eye for detail. Dick Van Dyke was considered for the lead role after the positive reviews he received from his dramatic role in the 1990 movie Dick Tracy (although the character he played in the movie was villainous and very different from the role of Mark Sloan).
Dr. Amanda Bentley, later Bentley-Livingston (Victoria Rowell), resident Pathologist at Community General Hospital and assistant County Medical Examiner, who is also Dr. Mark Sloan's straightwoman and medical partner. During the series, she married a military man, and had a son named C.J. Depending on the episode, she divorced him or he was killed in a plane crash. Later in the series, she adopted another boy, Deon.
Dr. Jack Stewart (Scott Baio, 1993-1995, seasons 1-2), a doctor at Community General Hospital and Steve's best friend, whom he often helped in his cases. He left to open his own practice in Colorado.
Dr. Jesse Travis (Charlie Schlatter, 1995-2001, seasons 3-8), a resident at Community General Hospital who Mark took under his wing. He often got involved in Mark and Steve's cases, with good intentions but not always good results.
Norman Briggs (Michael Tucci, 1993-1997, seasons 1-4), administrator at Community General Hospital and a close friend of Dr. Mark Sloan, even though he is often exasperated by him.
Jack Klugman also guest starred in season 4 episode "Physician, Murder Thyself", as a character very similar to his famous role in Quincy (he guest-starred again, in season 6 episode "Voices Carry" as a police Detective).
The episode "Must Kill TV" features a number of small cameos by TV personalities like Eric Estrada and Dr. Joyce Brothers playing themselves and a bigger one from Stephen J. Cannell as an over-the-top persiflage of a producer of action TV. The role is reprised in the two-parter "Trash TV".
Barry's children: Carey Van Dyke, Shane Van Dyke, Wes Van Dyke, and Taryn Van Dyke.
