#2. If It's a Blockbuster, the Star Better Be White (or Will Smith)
Quick: name a horror movie where one of the good guys is black. Well, hell, that's easy. One of the ship's crew in Alien was black, and some of the soldiers in Aliens. Danny Glover was the cop in Saw, Carl Weathers was one of the squad in Predator. Lawrence Fishburne in Predators. Hell, there are lots of them.
Now count how many of them survived to the end.
Pointing out that black characters die in movies isn't even clever anymore -- it's the kind of obvious, trite joke that bad movies make about other bad movies. But, inexplicably, it keeps happening. In the original Terminator, every black character shown on screen dies. In Transformers, the "black" robot who speaks in inner city slang dies.
There are some exceptions. You can bet that he won't die if he's played by a superstar like Will Smith or Eddie Murphy, who, not coincidentally, are among the very few black top-grossing actors at the box office. Otherwise, the black guy is there to get killed.
