Head of the Class is an American sitcom television series that ran from 1986 to 1991 on the ABC television network. The series follows a group of gifted students in the Individualized Honors Program (IHP) at the fictional Millard Fillmore High School in Manhattan, and their history teacher Charlie Moore (Howard Hesseman). The program was ostensibly a vehicle for Hesseman, best known for his role as radio DJ Dr. Johnny Fever on the sitcom WKRP in Cincinnati (1978–1982). Hesseman left Head of the Class in 1990 and was replaced by Scottish comedian Billy Connolly (in his first major American production) as teacher Billy MacGregor for the final season. After the series ended, Connolly appeared in a short-lived spin-off titled Billy. The series was created, and executive produced by Richard Eustis and Michael Elias. Elias had previously worked as a substitute teacher in New York City while hoping to become an actor. A revival of the series was ordered and was co-produced by Bill Lawrence's Doozer and Warner Horizon Scripted Television. It was released on HBO Max. Synopsis Head of the Class is mainly set in the classroom of academically gifted high school students, all in the Individualized Honors Program at Millard Fillmore High School in New York City. The IHP students comprised a diverse range of personalities, ethnicities, and academic specialties. For the first three years of the show, the IHP class had ten students. Arvid Engen (Dan Frischman) was a skinny, bespectacled nerd, mathematics expert, and budding scientist. Arvid's best friend was the overweight, wisecracking cynic Dennis Blunden (Dan Schneider), a computer whiz whose fields were chemistry and physics and who had a knack for getting the socially inept Arvid involved in various schemes. Both of them wanted to go to M.I.T. Alan Pinkard (Tony O'Dell) was an ultra-conservative preppy and egotist; his area of expertise was political science and he was a devout fan of Ronald Reagan. Alan competed for the highest grades in the class with Darlene Merriman (Robin Givens), a spoiled rich girl who was probably even more self-centered than Alan and whose specialties were speech and debate. Both Alan and Darlene held the ambition of being named class valedictorian. Sarah Nevins (Kimberly Russell) did not have any one particular area of expertise; she was the most down-to-earth of the IHP class and was once cited as having the lowest G.P.A. Maria Borges (Leslie Bega) was
