Marble Hornets
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. The series follows film student Jay Merrick as he investigates what happened to the student film Marble Hornets, abandoned by its director Alex Kralie after encountering the Slender Man.
There are 92 episodes on the Marble Hornets channel, with accompanying videos from a diegetic side-channel, totheark. As of late 2025, the series had over 700,000 subscribers and received 125 million views. The series also established the Slender Man symbol, which has since appeared in many other stories featuring the character. The reception for the web series has been mostly positive.
Marble Hornets spawned three spinoff sequel series entitled Clear Lakes 44, ECKVA, and Marble Hornets: Rosswood, the latter of which is also hosted on the Marble Hornets channel. The series would go on to inspire multiple web series in the same style as Marble Hornets, including EverymanHYBRID and TribeTwelve, with these types of web series given the nickname "The Slenderverse". In 2012, Blue Isle Studios announced its partnership with the Marble Hornets team to help write the script for the video game Slender: The Arrival. In 2015, a film adaptation entitled Always Watching: A Marble Hornets Story was released; critical reception to the film was predominantly negative.

Three years before, Alex abruptly ended the project after two months of production. Before cutting contact with Jay, Alex gave him the tapes containing raw footage from the film and told Jay to burn them, and never talk about it with him again.Choosing to watch the tapes, Jay discovers that the filming was haunted by an entity known as "the Operator". The Operator soon begins stalking Jay, driving him to set up cameras in his apartment for security. Even his YouTube uploads are stalked, as user "totheark" begins posting cryptic and threatening videos. Jay's investigation leads him to meet with one of the film's cast members, Tim Wright, who sends him to the abandoned house of another cast member, Brian Thomas, where Jay encounters an unknown masked figure.
Jay visits a red tower from the movie's production, discovering a hidden tape. In the tape, Alex abandons his cameraman Seth Wilson in a derelict building to the Operator, deeming all of the cast and crew of Marble Hornets as "gone".

The videos also reveal that Jessica was Amy's friend and roommate, who, when contacted by Jay in his investigation, was targeted despite her innocence.
The last tape shows Alex luring Jay and Jessica into the woods at the park under the guise of showing them something related to Amy's disappearance.

Jay tells the viewers he will keep them updated, and that he has a plan.
Season 3 (2012–14)
With no leads in finding either Alex or Jessica, Jay succeeds in tracking down Tim; unfortunately, Tim seemingly remembers nothing. Jay lies to Tim, telling him wants to work with him to finish Marble Hornets, to acquire behind the scenes footage. Tim is initially furious upon learning about Jay's true motives, but ultimately decides to continue assisting him. It is revealed that Tim does not remember anything he has done in his "masked" state, that he had been committed to a mental hospital due to hallucinations attributed to the Operator, and that his new medication is able to block him from switching to his "masked" state. Tim and Jay's investigation sees them repeatedly encounter the Operator, causing Jay to experience hallucinations. Tim's medication is stolen by his former accomplice, the hooded figure.Tim is revealed to have kept footage showing that he and the hooded figure are the ones responsible for Jessica's disappearance. This revelation drives Jay to attack Tim at his home and restrain him with zip-ties; however, Tim is later freed by the hooded figure. Tim and Jay separately set off to find Alex at an abandoned college campus. Jay finds Alex first, but is shot dead, and subsequently taken by the Operator. Tim learns that the hooded figure is Brian, and shortly after sees Brian fall to his death. Tim returns to his house to draw Alex to him, lighting his house on fire in an attempt to kill him. In the final confrontation with Alex, Alex reveals that he wants to kill everyone whom encountered the Operator; he claims that, in addition to Jay, he has already killed Amy, Seth, and Sarah, and he plans to kill Tim and finally himself. After a fight, Tim finally manages to kill Alex by stabbing him in the throat. Alex's body is also taken by the Operator.
A few days later, Tim reunites with Jessica, who survived the Operator attack in a hidden location. Tim lies to Jessica that Jay moved away, and that he will also be moving away. Tim lapses into a coughing fit as the camera distorts, then cuts to black. When the footage resumes, Tim is seen alone, driving away.

Episode overview
Cast and characters
- Troy Wagner as Jay Merrick: The man behind the "Marble Hornets" channel and the primary protagonist of the series. After rediscovering tapes given to him by former friend Alex Kralie, Jay begins uploading entries in an attempt to discover exactly what happened during the filming of Alex's student film Marble Hornets.

- Joseph DeLage as Alex Kralie: The director of the original Marble Hornets student film project, who abandoned his feature project in 2006 after encountering The Operator when shooting. A large portion of Season 1 consists of tapes he filmed for personal use and for his uncompleted student film Marble Hornets.
- Brian Haight as Brian Thomas: Brian was the lead actor in Alex Kralie's project and a member of Totheark. As the Hooded Man, he appears in many of the Entries and edits several of the Totheark channel videos. Initially presented as an antagonist – due, in part, to his somewhat acrimonious relationship with Tim – the Hooded Man is committed to Totheark's goal of facilitating Alex's death. As such, he assists Jay and Tim in their fight against Alex throughout the series. Brian falls to his death during a confrontation with Tim in entry #83.
- Jessica May as Jessica Locke: The woman who Jay meets in the second season of the series. She has an adjoining room with Jay at the hotel. In the last tape, it shows Alex luring Jay and Jessica into the woods before escaping. She is revealed to still be alive in entry #87. She is one of two characters that are confirmed to have survived the events of the series, the other one being Tim.
- Totheark: An anonymous group who makes cryptic video responses to the Entries throughout the series. These videos come from an accompanying side-channel with the same name. Seemingly antagonistic, their goal is to take revenge on Alex, as they believe him to be the source of The Operator, and use Jay, and later Tim, to get closer to finding Alex. Both Brian and Tim are members of the group.
- The Operator: An entity of unknown origin who begins appearing to Alex during the shooting of Marble Hornets and the primary antagonist of the series. It is later revealed that Tim was the first person associated with Marble Hornets to have come into contact with The Operator. Repeated exposure to the Operator is associated with a hard, painful coughing sickness.
Production
The show-runners did not have many people to help with the project: in the DVD commentary, they said the only people who could help were "the people who were doing the least," explaining the limited cast of Troy Wagner, Tim Sutton, Joseph DeLage and Brian Haight. The seven-month break in between seasons 1 and 2 was due to stress from the scope of the project. After returning back, the show-runners got more experimental with the series, involving a body camera for the hotel scene and involving professional actress Jessica May. In the DVD commentary, May was credited as being "so professional", and that the showrunners were shocked when she gave head shots for her audition.
For season 3, for entry #72, they had one day to shoot it, since the house belonged to Tim's extended family. The house was on the market for months, until they were alerted that the house had just been sold. The abandoned college seen in this season was the only place that they had permission to film in. For entry #85, it's confirmed in the DVD commentary that they actually poured gasoline and water on their front porch for the fireball effect. With a fire extinguisher off-screen, it was done in one take.
Marble Hornets amassed 97 episodes. The now-defunct THAC has said that the effects for the Operator will not be disclosed to keep the "fear of the unknown" in the character. In a 2019 livestream, DeLage claimed to play the Operator of its first scene, by duct taping pairs of flip-flops together for height and wearing pantyhose over his head. The entire series was edited with the software Sony Vegas Pro and Adobe Premiere. They also shot on the same Handycam camera for the whole series. In terms of sound production, Tim Sutton used an amateur homemade synth that he had experimented with the mechanics of, including bending the circuits, to create the sound distortion throughout the series.
