comfort zones and help them deal with the typical problems of kids their age, as well as using unorthodox methods of teaching the class subject at hand – might distract them too much from their studies. Ms. Meara was the level-headed assistant principal. There was some romantic tension between her and Charlie, although this ultimately came to nothing, and she later had a romantic friendship with Billy. In season 5, Mr Moore got his big break in Broadway and decided to quit. Billy Mcgregor, from Scotland, replaced Mr Moore. Unlike in the previous seasons, the students are allowed to call their new teacher Billy. The students get to prepare for senior year and the closing of Fillmore High School. In the series, the students often faced off against the rival Bronx High School of Science. Also, in every season, the IHP students produced the school musical. Musicals staged by the students included Grease, Little Shop of Horrors, and Hair. A number of someday-famous actors made appearances on the show, including Brad Pitt. Show open The opening of the show features various New York landmarks as well as Charlie Moore's journey to work every day. Charlie lives in a building in Hell's Kitchen occupied by a plant distributor on the first floor, who gives him a ride to the subway at 50th Street on the back of the truck before he makes his first delivery of the day. After Charlie grabs a hot dog for breakfast, he begins running into trouble as the subway station is on fire and he cannot hail any taxis to take him to the school. Forced to walk out of frustration, Charlie arrives late to class to the chagrin of Dr. Samuels but once he enters the classroom, his expression immediately brightens as he sees the students.
