Marble Hornets

Synopsis

Marble Hornets is an American found footage web series created by Troy Wagner, Joseph DeLage, and Tim Sutton. It is a pseudo-documentary based on the Slender Man online mythos. The first video posted to YouTube was on June 20, 2009, 10 days after Eric Knudsen made the original images of Slender Man on the Something Awful forums. It follows film student Jay Merrick (Wagner) as he investigates what happened to the student film Marble Hornets, abandoned by its director Alex Kralie (DeLage) after encountering the Slender Man (called "the Operator").
