While attending his first semester at Cal State Northridge, Zabka began auditioning for The Karate Kid (1984).

Participating in the film inspired Zabka to learn the martial art of Tang Soo Do and he later earned his second green belt. The film's final scene was filmed at Cal State Northridge's gymnasium, and Zabka later jokingly commented on this stating: “So I went to college as a student and came back by the end of the semester as one of the stars of Karate Kid.” • Illustration — Zabka in 2018 Later in the 1980s, Zabka appeared in the comedy movies Just One of the Guys (1985) and Back to School (1986).
