Excelsior High School, originally named Excelsior Union High School, was founded in 1903 and located on Walnut Street in Norwalk, California. The current campus was built in 1924. The campus sustained substantial damage to the administration building, auditorium, and other buildings in the 1933 Long Beach earthquake. Although the earthquake occurred after school hours, one student died when an internal wall in a portion of the boy's gym failed. Its last graduating class was 1981.

Grease 2 is a 1982 American musical romantic comedy film and the sequel to the 1978 film Grease, adapted from the 1971 musical of the same name by Jim Jacobs and Warren Casey. Originally titled More Grease, the film was produced by Allan Carr and Robert Stigwood, and directed and choreographed by Patricia Birch, who choreographed the original stage production and prior film. The plot returns to Rydell High School two years after the original film's graduation, with a largely new cast, led by Maxwell Caulfield and Michelle Pfeiffer in her first starring role.
