He Knows You're Alone on AllMovie

In this fairly frightening slasher-horror film, sweet young Amy Jensen (Caitlin O'Heaney) and her friends decide to all get married together. Unfortunately, all the guys go on vacation, leaving the women at the mercy of a psychotic killer (Tom Rolfing) who goes after brides with a big knife. Amy must seek help from an obsessed cop (Lewis Arlt) and her nerdy friend (Don Scardino) who works at a morgue. The familiar supporting cast includes Tom Hanks in his big-screen debut, and '80s standbys Russell Todd, Paul Gleason, and Dana Barron. This one has some scary moments despite the clichéd plot and the obligatory severed head in a fishbowl, especially a stalking scene in a tailor's shop and the tense morgue chase at the end. The most memorable sequence, involving a murder at a movie theater, was later restaged almost shot-by-shot in Scream 2 (1997).
