I'm stuck...

How come all of a sudden, I cant think of how to start actually writing my project. I'm working with Theima and she is absolutely no help. Okay, okay, she's trying, but I'm really stuck. We're supposed to be looking at how different races act in movies when they assimilate/ penetrate other races characters. We decided to look at different movies like Beauty/Barbershop, White Chicks, Malbu's Most Wanted, and MTV's Blowin' Up. It's not that I dont have a focus, I just dont have a train of thought right now. This sucks.
