Spoiler-Free Synopsis
Read MoreCollapse
He Knows You're Alone is a routine slasher movie, directed by Armand Mastroianni, about a young bride menaced by a maniacal killer. She seeks the help of a former boyfriend, and as they try to discover the identity of the killer, the body count mounts. This film, neither stylish nor clever, has little to recommend it, though trivia lovers should note the appearance of veteran actor James Gleason and -- in a supporting role, Tom Hanks in his film debut. He Knows You're Alone was also released as Blood Wedding, not to be confused with the beautiful flamenco dance film by Carlos Saura (aka Carmen).
