I Wanna Hold Your Hand is a 1978 American historical comedy film directed by Robert Zemeckis, written by Zemeckis and Bob Gale, and starring Nancy Allen, Bobby Di Cicco, Marc McClure, Susan Kendall Newman, Theresa Saldana, Eddie Deezen, and Wendie Jo Sperber. Its story line follows a disparate group of teenagers over the course of one day in New York City as they attempt to gain entry to the Beatles' first live appearance on The Ed Sullivan Show on February 9, 1964. The film also examines the mass hysteria surrounding the event, dubbed "Beatlemania" for the fervency of the group's fans. The film's title is derived from the Beatles' 1963 song of the same name.
