As somebody who actually had to go through a discrimination case with my job I'll reserve judgement on this story. But a few things seem off here. 1) This 'firing' came in 2003, so why wait 4 years to file a lawsuit? 2) If John Singleton was the director why wouldn't he have made a big stink if his black assistant director was fired because the studio wanted a white assistant? And if the studio felt that strongly about race, wouldn't they have just hired a white director instead of Singleton in the first place? But like I said, I'll reserve judgement.
