Mr. Hall
Mr. Hall, played by Wallace Shawn, worked at Bronson Alcott High and was one of Cher and Dionne’s teachers. In fact, he was the one who Cher tried to set up with a dowdy teacher named Mrs. Geist in order to make him less miserable and distract him from teaching, but it didn’t really go so well. It did offer some comedic relief that’s making us want to binge-watch the movie all over again, (and why not, even the Nickelodeon TV show!)
