The Wiz (1978)

Factual error: Dorothy tells Miss One that she lives at "433 Prospect Place." Dorothy is supposed to live in Harlem. Any New Yorker knows that there is no Prospect Place in Harlem. In reality, Prospect Place is in Brooklyn and is, in fact, where the street scenes for "Harlem" were filmed.

Scarecrow: Barnum said there's a sucker born every minute.
Tinman: I was there when he said it, but I never thought I'd be one of them.

Trivia: According to an unauthorized biography, "Call Her Ms. Ross," Diana Ross was hospitalized and neaarly blinded by the lighting effect used for the movie.
