I was thinking that our little horror film needed an explanation. It came as an assignment in class: Get a partner, take a camera, and go film something, hopefully related to your subject area. You have a half-hour. Go.
So, being English majors, my partner and I headed towards the library. And we . . . filmed stuff. It was only later, in "post," that we decided what it was going to be about. Once we stuck those shaky and old-timey filters on the library shot, we realized it was a scary movie. So we edited the rest to be such.
It started out a "how-to" movie for using the library, and ended up . . . very entertaining.
Well, we laughed a lot as we were making it, anyway. And in the end, isn't that what matters?
