See Mormon Film: Key Films of the Fourth Wave
This film grew directly out of the refurbishment of the Hotel Utah as the Joseph Smith Memorial Buildling, a project initiated by Gordon B. Hinckley. The storyline was largely Hinckley's, although the actual screenwriting was done by writer/director Kieth Merrill. Production began in January 1990; it was filmed on locations in England and America, with a principle cast of thirty, a cast of extras at 3,000, and a crew of 120. The rough cut was deemed overly long and it was hence cut down to its final length to accomodate hourly screenings. The new building was dedicated on June 27, 1993, and Legacy
premiered on July 3.
Both the film and theater were an immense success, including on the latter's video release in 1997. When a new film, The Testaments of One Fold and One Shepherd,
premiered in the cinema it was renamed the Legacy Theater. The term has come to be used on LDS genealogical software and other items.
