There's a part when Eddie Murphy
's character is throwing one of the Beverly Hills thugs over a buffet table at a fancy "Harrow" country club. If you watch is closely, or freeze frame just as his face is seen, you can clearly notice that it's a stunt man throwing him over the table. In fact, the stunt man looks kind of like Richard Pryor!
But he's clearly built better than Murphy (or Pryor for that matter).
Also, watch the face of the actor whose character was thrown over the table... The mess on his face changes type and position each time you see him in the remainder of the scene.
