That the year says 1989 when it was made in 1987. How do I know? I was a senior at that school in 1987. Except for the speaking parts, those kids you see around the school actually went there. I probably would have been in the background myself if I didn't leave early for a class at a different school.
Something else, especially if you are into the NBA. In a shot when they are in the courtyard of the school, look in the distance at the payphones and you will see a tall redhead with a lettermans jacket on. That is Adam Keefe, who played for the Atlanta Hawks, Utah Jazz and the Golden State Warriors before retiring.
