In this movie, the guy playing the role of Braxton's (Richard Pryor) parole officer, Donald, is seen driving a white Cadillac Seville with a RED interior during the film's Philadelphia scenes. The scene is the one where he's sending the group off on their trip. When he tracks them down later in the movie, trying to get the group to return to Philly, he's driving the white Seville, only this time, the interior is WHITE. Neat trick.
