Sleep No More

2018 ·1h 31m · ★ 4.5 (43)

It's 1986 and a group of grad students are close to discovering what happens to the human brain after staying awake for 200 hours, but something goes terribly wrong with a test subject. After their department is shut down, the team moves forward in secret - only this time on themselves.

Why it matters

A tense dive into sleep deprivation’s psychological abyss that blends body horror with creeping paranoia in a retro-science thriller setting.

  • Practical effects amplify the physical toll of sleeplessness with visceral, unsettling detail reminiscent of Cronenberg’s body horror.
  • The ’80s academic backdrop grounds the story in a pre-digital era of experimental obsession and isolation, heightening the dread.
  • Perfect for fans of slow-burn psychological horror who appreciate atmosphere over cheap jump scares.
  • Flawed pacing occasionally undercuts tension, but the film’s commitment to exploring the brain’s darkest vulnerabilities rewards patient viewers.
