From the low-budget horror films that exceeded expectations, movies from the horror genre typically make use of a shorter runtime than their peers. Unlike other brands of cinema, the success of such films is not contingent upon elements that other genres traditionally rely on. The goal of these movies is to elicit fear, revulsion, and suspense among their audience. As such, they don't necessarily have to rely on an intricate plot or nuanced character development to produce a successful and memorable viewing experience.

With that being said, several preeminent films from the genre have effortlessly bucked this trend, proving that a lengthy running time doesn't necessarily constitute a death knell for successfully maintaining terror and tension across a longer period of time. From modern stand-outs to classic offerings from the genre, a number of the best horror films of all time have garnered beloved status despite boasting a lengthy running time, providing a glorious pay-off for any viewers willing to stick around until the end.

10 Midsommar (2019)

3 The Invisible Man (2020)

Running Time - 124 Minutes

Loosely based on H.G. Wells' 1897 novel and serving as a remake of the 1933 film of the same name, The Invisible Man stars Mad Men standout Elisabeth Moss as Cecilia Kass. Directed by frequent James Wan collaborator Leigh Whannell, the 2020 movie sees Kass ruthlessly tormented by her abusive former boyfriend through the use of a high-tech suit that renders the wearer entirely invisible.

The surname of Cecilia's abusive ex-boyfriend, Adrian Griffin, is a tip of the cap to H.G. Wells. In Wells' original novel, the Invisible Man is referred to only as "Griffin."

Whannell's white-knuckle horror movie is such an electrifying piece of cinema that The Invisible Man's running time feels more like 124 seconds.

2 The Substance (2024)

Running Time - 141 Minutes

Arguably one of the best body horror movies of all time, Coralie Fargeat's The Substance stars Demi Moore as Elisabeth Sparkle. An aging former A-lister, the 2024 film chronicles Sparkle's attempts to recapture her youth through the use of an experimental substance that creates a younger version of herself, as well as the nightmarish results that arise from abusing it.

Given the fact that seminal subgenre offerings in the vein of The Fly and Tusk only last 96 and 101 minutes respectively for context, The Substance is remarkably long for a body horror film, boasting a runtime of just under two and half hours at 141 minutes. Fortunately, every single second of Fargeat's nightmarish picture is worth the wait. An audacious horror film with a healthy portion of wicked black comedy, The Substance lingers in the viewer's mind long after the credits roll.

1 It (2017)

Running Time - 135 Minutes

An adaptation of Stephen King's 1986 novel of the same name that features one of his best villains, 2017's It is a consistently riveting watch despite a lengthy horror movie running time of 135 minutes. With particular praise directed towards Bill Skarsgård's haunting bow as Pennywise and the superb performances from the adolescent versions of The Losers Club, the first half of Andy Muschietti's two-part take on King's novel is a worthy adaptation of one of horror's most iconic and memorable characters.

Ironically, it's also worth noting that the film's sequel, 2019's It Chapter Two, actually boasts an even heftier duration at a whopping 169 minutes. However, in sharp contrast to the well-received original, the sequel was largely lambasted by critics, with specific criticism actually directed towards the movie's lengthy running time of nearly three hours.
