There is another movie I'm looking for. Maybe someone can help.
Things I remember:
# There was a killer in it, dressed as a police officer. He had big eyes and a very dull face.
# It was about people (4 teenagers I believe) who were traveling to a house by car. They had to take care of the house over summer or something like that.
# At the beginning of the movie they noticed that a police car is following them, but ignore it.
# The house was near the woods and the killer regularly came to kill one of them. Often he first talked to them and said he wanted to help, just to lure one of them away and kill him/her.
# It was a very stupid low budget B-movie. It was so bad that it was good and funny. I think it must be from the 80s or 90s.
Any idea?
