The New Adventures of Heidi (alternate title Heidi's Christmas) is a 1978 American made-for-television musical comedy-drama film updating the Heidi character to the present time and shifting the action from Switzerland to New York City. The film was released theatrically in Spain and Australia. Charles B. Fitzsimons had the idea to turn the film into a musical with comedy writer Buz Kohan writing ten songs for the film, sung by the stars Katy Kurtzman, Burl Ives, John Gavin and Marlyn Mason who played Heidi on stage in 1954 at the Player's Ring Theatre in Hollywood.
