Actor John Leguizamo has blasted Hollywood star Kevin Costner, insisting the Dances With Wolves actor launched into a self-obsessed rant on the set of 1990 movie REVENGE. Leguizamo lashes out at Costner in his brutally honest new book PIMPS, HOS, PLAYERS, HATERS + ALL THE REST OF MY HOLLYWOOD FRIENDS, recalling the time Costner took him aside to give him a lesson on movie lighting. The Summer of Sam actor writes, "(He told me), 'I want to teach you something son. I'm going to teach you something about lighting. "Get out of my light. Now if you can manage that we might have a good movie, son.' "I'll never forget that. Never block a star's light. Got it. C**ksucker."
