This is the first time that we see Kelly's parents together along with Zack's parents. In the show, Kelly's father was seen in the episode "The Prom" while Zack's parents made separate appearances during the show's run.
Jessie (Elizabeth Berkley) only makes a brief cameo appearance towards the end of the film because Berkley was working on Showgirls (1995) at the time.
