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.
When Heidi's grandfather finds he is losing his sight he does not wish to tell Heidi, but he makes her live with her relatives, Cousins Tobias and Martha to attend school in a large city.
Through his secretary Mady, Heidi joins Elizabeth and her busy widowed father Dan Wyler for a Christmas in New York City.
With the low budget of the television film precluding having the film shot in Switzerland or New York City, the crew shot Swiss sequences in Snowmass, Colorado with imitation red poppies and the Westin Bonaventure Hotel in Los Angeles, California with imitation snow.
