Titled "Nikita" during filming, Producer Art Linson and Warner settled on a new title during post production that Warner owned -- "The Specialist". However, two months before the film was to be released, Linson was contacted by Warner exec, Bruce Berman, and told that the title would be changed to "Point of No Return". Warner gave the working title to an upcoming Steven Seagal vehicle which was yet-to-be-filmed. Ultimately that movie, The Specialist (1994), ended up starring Sylvester Stallone after Seagal dropped out.
