 In the scene where Richard Pryor (Gus Gorman) is trying to get Gavin  OHerlihy (Brad) drunk (where pryor is wearing the giant cowboy hat) there is  extended dialogue on the UK TV version (cut out from the UK video release)  where OHerlihy talks about his high school nickname The Phili/filly flash.  Which is then referenced a couple of minutes later when pryor is dragging him  into the computer room.
