3 movies i remember but just canīt figure it out what the title is.
1.
A group of friends find a alien and bring it home and chain it to a table and hold it hostage.
But after a while it escapes and starts killing the guys.
I remember a death scene, that the alien pulls someone's intestins out, but that's all i can remember
2.
A group of computer geeks are making a female(i think) robot, this robot goes on a rampage and starts killing everyone.
3.
Some crazy man with his truck starts following people and kills them one by one.
I remember that the man had a mechanical arm or leg not sure.
And there was a scene where he follows some guys in a corn field.
Hope you guys can help me find the movies i'm looking for.
