Tom Hanks in He Knows You're Alone (1980)
Long before he made us laugh in Big, before he made us cry in Forrest Gump, and way before he made mega-blockbusters like The Da Vinci Code, Tom Hanks was in a simple teen horror flick called He Knows You're Alone. The tagline of the movie was: "Every girl is frightened the night before her wedding, but this time...there's good reason!" A young bride-to-be is being stalked while her future husband is out of town. Hanks plays the grieving boyfriend of another victim. Maybe the promise of a shelf full of Oscars would have cheered him up.
