"Why Do You Want to Work Here?"

Yeah... that question. I'm guessing it wouldn't look very good/convincing if I told them "I need money, please hire me." and I always draw a blank on what I should write here, regardless of where it is.

Currently I'm trying to apply to a movie theater in my area so if you have any ideas that I could use, or just general tips on approaching this question in the future, that would be great.
