Key Budget Allocation Categories

▸ Practical Effects, Prosthetics & Makeup Horror productions invest disproportionately in practical effects — prosthetic applications, animatronics, blood and gore effects, and creature suits. A single hero creature suit can cost $50,000–200,000.

▸ Atmospheric Production Design & Cinematography Creating dread through environment is essential. Abandoned locations must be secured and dressed, lighting rigs designed for shadow and tension, and sets built to enable specific camera movements and reveals.

▸ Sound Design & Score Horror is arguably the most sound-dependent genre. Foley work, ambient textures, frequency manipulation, and jump-scare stingers require specialized sound designers working with unconventional techniques.

PRODUCTION NOTES

▸ Development

In May 2016, news outlets reported that Sony Pictures had started developing Slender Man, a film based on the supernatural mythical character created by Eric Knudsen, with the screenplay to be written by David Birke. Sony's Screen Gems was in talks with Mythology Entertainment, Madhouse Entertainment, and It Is No Dream Entertainment to produce and distribute the project. In January 2017, Sylvain White was announced as the director and the producers would be Mythology's James Vanderbilt, and William Sherak, Madhouse's Robyn Meisinger, and No Dream's Sarah Snow. Ramin Djawadi and Brandon Campbell composed the score.

A casting was revealed in May 2017, where Lea van Acken, Julia Goldani Telles, Jaz Sinclair, Annalise Basso, Talitha Bateman, and Alex Fitzalan joined the cast. In July 2017, Kevin Chapman was also added to play an emotionally defeated, alcoholic father. While filming and Principal photography on Slender Man began on June 19, 2017, in Boston and concluded on July 28, 2017. Prior to the release, the producers shopped Slender Man to other distributors following disagreements with the studio regarding the release and marketing strategy.

▸ Marketing & Release

On January 2, 2018, the first teaser poster was revealed, followed by a teaser trailer the next day. Reactions were mixed, with some online publications describing the trailer as taking a "traditional, low-budget horror route". Other publications noted its release coming four years after the Slender Man stabbing in Waukesha County, Wisconsin in 2014. After the trailer's online debut, Bill Weier, the father of one of the children convicted in the stabbing, protested its production and release as "extremely distasteful" and advised local theaters to not screen Slender Man. As a result, Marcus Theatres, a theater chain based primarily in Wisconsin, chose not to show the movie. Additionally, Bloody Disgusting reported that Screen Gems had required the producers to meet a PG-13 MPAA rating and that several scenes had been cut over fears of public backlash (including several scenes that had appeared in trailers), resulting in narrative and continuity issues in the final film.

A second trailer was released on July 26, 2018. Slender Man was released on August 10, 2018. It was previously slated for May 18, and then August 24, 2018, before the finalization of its release date. Slender Man was released on Digital HD on October 19, 2018, and on Blu-ray and DVD on October 30, 2018 by Sony Pictures Home Entertainment.
