There are two that I really just can't remeber and it's been driving me crazy. I saw them both around 2000 on TV. One was a romantic comedy that was in theaters. I believe it was about a famous actor who's career was going downhill so they set up a sort of bachelor-esque reality show to revitalize his career. The leading actress was blonde and she unwillingly became a contestant on the show. I believe she ended up in the final two and decided to act obnoxiously so she doesn't get chosen because she liked some guy on the crew for the show.

The second one was a little dated looking. It took place somewhere in the countryside. It involved a family going on a murder spree. I don't remember if they did for particular reason though. They killed a lot of people including a teenage girl whose body was then thrown into a swamp and a doctor who was treating the oldest son. The mother put a pillow over the doctor's head and shot him. It ended with a big shootout.
