1 FILM 4 GENRES

1 FILM 4 GENRES Is Available To Watch On YouTube now! The Private Investigator is anomalously tipped off about the disappearance of his ex wife, he searches the house for clues when the phone starts to ring. No one knows where he is, no one lives here, so who is calling? I edited the same film into 4 different genres and 4 different stories and was originally for my university dissertation, Perhaps I'll make the original full story at a later date. Can you guess which film was the original?
