Pressley actually talked about the film about six months before it's DTV release on Conan. She said that when she signed up for the film, it was a couple months after Scary Movie blew up big, so she thought that she was dealing with a spoof. She read the script and thought it was hilarious.
Only thing was that when she showed up to the set, it wasn't being played for laughs, and she realized just how screwed she was.
Bad movie, but not the worst ever made.
Ax' Em and Creepin', both from York Entertainment, are easy candidates.
