Hannah was originally named Kat (short for Katherine), but her name was later changed to avoid any reference to KITT.
The early drafts of the script were far closer to the original series even including KITT (who would have been a female); however, the makers believed at that time there would be no high-tech cars. Ultimately this movie had little in common with Knight Rider's basic concept, except the title, a talking car, and the "one man can make a difference" concept.
