ok there was this movie I saw when I was little but all I can remember is that there where group of people getting killed by there own twin or clone and I remember one scene where a girl was getting chased by her clone down a hallway

I don’t remember much about the horror movie but I do know there was a girl killing people and the there was a scene where she killed somebody while he was lifting weights and she had dinner with the dead bodies

Horror mystery movie: there this movie where a guy kills women but while trying kill one he falls down the stairs and forgets his memory later on in the movie he has a wife but continues to see some of the Victims he killed then at the end he gets his memory back then tries to kill his wife
