There is a scene in one of the Die Hard movies where the SWAT team attempts to breach the Nakatomi Plaza building. Some of them walk through the bushes and one of the men scratches his hand and says "Ow!". That guy sounds like Richard Pryor and looks pretty much just like him too.
That clip has since caused confusion as to whether that actor was Pryor or was just an uncredited bit player.
Some think it was indeed the comedian. That scene was hilariously out place and particularly funny, just how we know Richard Pryor was - he could make anything funny.
But checking his IMDb profile, the comedian did not receive any credit for this appearance nor it was mentioned in any articles online.
Richard Pryor died of a heart attack on December 10, 2005. He was 65.
