The "Balabushka" in the movie is based on the J-18, but different. The movie cues used notched diamonds. The cue used in the movie was unique. The various N-7 variants down the years have been based on the movie cue, but never the same, as Dan Janes wanted the movie cue to stay unique. The most radically different N-7 versions have been the gold letter edition, with the additional forearm inlays, and the current model, which did away with the white butt cap entirely and has a "Hoppe ring" instead.
