Delusion: “He ordered her to murder him, or was it a delusion?” An experiment in terror in broad daylight. Per Larry Cohen: 'If you’re familiar with other films I wrote, like “Daddy’s Gone A-Hunting” and “Misbegotten” and “Invasion of Privacy” as well as my “It’s Alive” films, then you will understand the connection in theme. But without giving anything away, before you see it, just enjoy “Delusion” as a psychological thriller and draw your own conclusion.'
