Fright Night (1985)

For young Charley Brewster, nothing could be better than an old horror movie late at night. Two men move in next door, and for Charley with his horror movie experience, there can be no doubt that they are a vampire and his day guardian. The only one who can help him hunt them down is a washed-up actor, Peter Vincent, who hosts Charley's favorite TV show, Fright Night. But Vincent doesn't really believe that vampires exist.
