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.
