While only playing a minor role,Tom Hanksfirst appeared on-screen in theHalloween-inspired movieHe Knows You’re Alone(1980). While Hanks has had some choice words about his debut, the film does have some intriguing elements for slasher fans to explore.
Inspired by Halloween and echoing an early form of self-awareness in horror that would come to a peak with 1996’sScream, we take a closer look at the little-known slasherHe Knows You’re Alone.

He Knows You’re Alone Plot and Cast
A serial killer begins targeting soon-to-be brides in an act of vengeance, having been rejected by an ex-girlfriend years previously. A cop, Len Gamble, having had his fiancée murdered three years previous by the same man, attempts to defend the city against a potential threat. At the same time, Amy Jensen is preparing for her wedding and has become unaware she has been made the next target of the killer, though her paranoia grows as she starts to believe a tall man is stalking her.
He Knows You’re Alonewas directed by Armand Mastroianni, who would direct several movies and TV series, including episodes ofTales from the DarksideandFriday the 13th: The Series; his debut slasher remains his most well-known work. Lewis Arlt played the role of Len Gamble and would have a career of little significance. However, the movie would boast some notable names; Don Scardino would go on to succeed as a director of TV and film, notablyworking on30 Rock; James Rebhorn went on to have roles in prominent films like Independence Day; Dana Barron would go on to play Audrey Griswald inNational Lampoon’s Vacation.

He Knows You’re Alone Was Inspired by Halloween and Became a Precusor to Scream
1978’sHalloweencame to define the slasher genre, and while there were films that had come out previously (the Proto-Slasher) –Black Christmas(1974),Peeping Tom(1960),Deep Red(1975),Psycho(1960) –John Carpenter’s masterpiecewould launch the sub-genre into unparalleled popularity.Halloweenbecame the blueprint and would shape other era slashers; everything from the popularFriday the 13thfilms toSleepaway Campto lesser cult hitsMy Bloody ValentineandThe Slumber Party Massacremay not have existed withoutHalloween. While not reaching the same notoriety as any of the titles mentioned above,He Knows You’re Aloneis another direct example of a movie released shortly afterHalloweentrying to tap into the booming interest in the genre.
The most notable slasher film to predateScreamis undeniablyFriday the 13th Part VI: Jason Lives; breaking the fourth wall and having characters predict their ghastly demise set up the tongue-in-cheek humor that would appear in many other films. However,He Knows You’re Alonemay be the first case of having a self-aware character in a horror film, breaking that fourth wall to present the audience with the fact that they are watching a horror movie.

Tom Hanks' character, Elliott, who is introduced in the latter half of the film, openly discusses how horror movies work and evenpoints to the tropeof the stalked protagonist when he tells Amy; “Have you seen this man while you were with us?” and “The hallucination will only manifest itself when you are alone,” which is followed up by her seeing him alone despite him being in a crowd. It is a small moment, but it is a bit of clever writing that often gets overlooked when discussing the history of self-aware horror movies.Scream 2would even acknowledge this connection, with the opening scene parodyingHe Knows You’re Alone.
