The Next Karate Kid - Production

Production

All the interior and exterior high school scenes were filmed on the Brookline High School campus, except for the scene in the gymnasium. The exterior shot is the Brookline High School gym, but the interior was Cousens Gymnasium at Tufts University. Other scenes from the movie were shot in the Boston area. For example, the scenes at Julie's house were filmed in nearby Newton.

The first three movies in the series, which featured Ralph Macchio as Daniel, were set in Los Angeles. In this movie, the setting is changed to Boston.

Because Hilary Swank could learn the advanced "flashy" moves and had trouble with the beginner moves, Pat E. Johnson, the martial arts choreographer, awarded her with a "Pink" belt, a mix of the white (beginner) and red (the one just under black in that particular style).

In all the four movies, the reunion scene is the only time Miyagi actually wears his Medal of Honor. The Medal of Honor is worn on a silk ribbon around the neck, not pinned through a jacket. The only other neck order issued by the United States is the Legion of Merit.

Conforming to the title changes of the first, second and third Karate Kid films for their releases in Japan, The Next Karate Kid was renamed Best Kid 4 (ベスト・キッド4/Besuto kiddo 4); the major and obvious change is that this movie's translated title now explicitly identifies it as the fourth in the series.

John G. Avildsen, the director of the first three films in the series, dropped out of this one in favor for 8 Seconds. As a result, Christopher Cain took over in the director's chair.

The Next Karate Kid is the only film in the series where screenwriter Robert Mark Kamen, who had written all three of the others for the screen, did not have a writing credit.
