An entire day's worth of film was lost when it was believed to have been accidentally left in a New York City taxicab. The film was never recovered.
This is a remake of the French movie Little Indian, Big City (1994). The plot follows the original fairly closely, except that the original was set in Paris rather than New York, and Mimi-Siku climbed the Eiffel Tower rather than the Statue of Liberty.
In addition to relocating from Paris to New York, the character Mimi-Siku was made much older than the preteen in the French version. This was largely due to Americans' general discomfort with young love, under the explanation that "a teenager can get into more trouble." Additionally, despite American Mimi-Siku's having lived in the wild, there's less difference in the skin tones of the two male leads than in the original French film. This was done to emphasize their kinship.
The book Mimi-Siku reads aloud at the end is "The Call of the Wild" by Jack London.
At one point, when Mimi walks outside along a ledge at Charlotte's office, a man exclaims: "He's doing a Fay Wray!" This is in reference to the actress Fay Wray, whom was the lead in King Kong (1933) where she was carried to the top of the Empire State Building by King Kong.
After shooting Charlotte's cat with the dart, Michael exclaims "Oh no!" in the same grunting manner as Tim Allen's character, Tim Taylor, in Home Improvement (1991).
Tim Allen and Martin Short would later star together in The Santa Clause 3: The Escape Clause (2006).
When Michael, Richard and Mimi-Siku are visiting Jovanovich after they ring the doorbell, Jovanovich yells "Open damn door!" then he says "Chort vozmi!", which in Russian literally translates to "The devil take it!"
