The movie is a comedy about a family of aliens, two parents and their daughter, who come to planet earth. The parents kill people, but justify it because their victims are all convicts, rapists, and thieves. Meanwhile, the daughter falls in love with a human from Earth.

This sounds a little bit like the coneheads?

It kind of sounds like CONEHEADS with dan akroyd and chris farley! But I'm not sure, you can always check on imdb.com, type in coneheads and see if that is what you are describing.

Brittany:)

The only problem with Coneheads is they didn't kill anyone.

Sounds a little like Meet The Applegates, or, Parents.

It's called Alien Avengers! Great Movie

Ahhhhh. How did you find it wolf? Is there another web site that gives good info?
