The best movies now are called 'thrillers.' Because if you use the word 'horror,' people's associations are straight-to-video crap.

I think that horror films have a very direct relationship to the time in which they're made. The films that really strike a film with the public are very often reflecting something that everyone, consciously or unconsciously feeling - atomic age, post 9-11, post Iraq war; it's hard to predict what people are going to be afraid of.
