When I was a kid I rented two different movies and have not been able to figure out the titles because of the lack of memory of the films. I do know some specific scenes and would like help.

The first one I have a bit more to go on.
The vhs box art was like the old farmer painting with a old farm picture of the woman and man farmer holding a pitch fork.
The movie I believe was a group of young adults and they are on some sort of island I believe and find a house with a weird family. I remember one scene is a swing set on the edge of the rocks and the girl keeps getting pushed higher and higher and the swing snaps and she flies off the cliff.
The other are being killed in the house by the rest of the creepy family.
There was a mom and dad a big country guy who is some sort of special kid and maybe twin girls. The girls may be wrong.

The other is just one small scene and probably will never be known. Also when I was a child around 1993 when I watched it. So could have been any year before that. At the very end of the movie when everything seems to be fine and the guy seems to be relieved he is laying on his bed or in a chair and holding a remote flipping threw the channels and all of a sudden the wall comes crushing in and hordes of zombie looking people come crushing in.

If anyone could help at all it will have helped me with a 20 year search .
I know not a lot to go on but thanks to anyone who tries.
