Frances Hodgson Burnett's novel was serialized in The American Magazine between 1910 and 1911. Matthew Boulton's name is misspelled "Mathew" in the onscreen credits. A December 1946 Hollywood Reporter news item indicates that Claude Jarman, Jr. was orignally slated for the part played by Dean Stockwell. A Hollywood Reporter news item on April 7, 1947 indicated that M-G-M had planned to shoot the film in England on a "newly erected studio," but the film was eventually shot on the M-G-M lot in Culver City, CA. The film's Technicolor sequences were those that took place in the garden. Modern sources credit Marni Nixon with dubbing Margaret O'Brien's singing voice. Other film adaptations of Burnett's novel are The Secret Garden, a 1919 Famous Players-Lasky Corp. production, directed by G. Butler Clonebough (a pseudonym of Gustav von Seyffertitz) and starring Lila Lee and Spottiswoode Aitken (see AFI Catalog of Feature Films, 1911-20; F1.3908); a 1984 BBC production, also entitled The Secret Garden, directed by Katrina Murray and starring Sarah Hollis and David Patterson; and a 1993 Warner Bros./American Zoetrope production, The Secret Garden, directed by Agnieszka Holland and starring Maggie Smith and Kate Maberly.
