The box-set contains 6 films
Deadly Friend (1986) - Which is a less talked about horror film from Wesley Craven's filmography.
Dr. Giggles (1992) - Which is a oddball 90's horror comedy slasher.
Eyes of a Stranger (1981) - Which is a surprisingly effective little Thriller with some slasher elements.
From Beyond the Grave (1974) - A pretty solid Anthology film from the 70's starring Peter Cushing and Donald Pleasence
The Hand (1981) - A crazy psychological thriller directed by Oliver Stone
Someone's Watching Me! (1978) - Driected by the big homie Johnny Carpenter, A TV movie that's plays with that Hitchcock thriller style. A precurser to Halloween.
Overall I highly recommend this boxset. Especially for the price.
