Nickelodeon's first feature film.
Many theatrical versions included the pilot episode of Hey Arnold! as a short before the start of the film.
The letters that Harriet writes on the top corners of the pages in her notebook spell "EVERYBODY HATES ME."
The film started shooting on October 11, 1995 which was Michelle Trachtenberg's tenth birthday.
Rosie O'Donnell (Ole Golly) remembers reading the novel when she was ten years old, and it was one of her favorite novels as a child. She immediately accepted the role of Ole Golly when it was offered to her as a result without reading the script first.
