''Film/EventHorizon'' is about a ship that goes ToHellAndBack. By the time it's over, audiences [[NightmareFuel feel the same]].

* Aside from the EyeScream and {{Squick}} elements that keep cropping up over and over, there's the part where we finally see [[http://www.youtube.com/watch?v=RthgXpWDv6A the deciphered message]], and it's just blurry enough to make you wonder if you really saw the unspeakably horrible thing you thought you saw [[spoiler:the various crewmembers of the titular ship doing to each other under the influence of the dimension they had passed through]], or if it was just your imagination.... ''and the only way to find out is to watch that sequence again''. It's not often one is willing to put the remote down and walk away rather than go back and confirm an image, but ''Event Horizon'' pulled it off.
** ''[[ApocalypticLog Liberate...]]'' ''[[spoiler: [[ApocalypticLog tutemae...ex inferis.]]]]''
* Wanna know something worse? A significant amount of footage was ''deleted'' from those unspeakably horrible sequences in the final cut of the film. The original version was more explicit.
** [[http://www.youtube.com/watch?v=ZK1debnXYlA Here]] [[SchmuckBait are some of the scenes.]]
* The only thing matching the ship's log would be the visions of Hell that Weir projects into Captain Miller's head, where we see the crewmembers' bodies wrapped in barbed wire, disemboweled, or impaled on spikes with their bodies crawling with maggots. Since each scene lasts only a fraction of a second, it leaves the viewer thinking "what the hell did I just SEE!!??"
* A comparatively little one: when they're first exploring the bridge, lightning from the storm below their orbit briefly lights up the walls near the windows...which are splattered with blood, tendons, and what look like they might be ''bones''. It's only for a split moment, but it makes you stop and have to wonder what the hell ''happened?!'' Given what we later see of the crew's log...''ick'' is a bit of an understatement.
* The more lingering part of the film is that Dr. Weir is set up as a {{Woobie}}, with Captain Miller being the JerkAss. The poor man goes through so much pain that you feel bad that he becomes a Cenobite, and you ''nearly'' end up RootingForTheEmpire - til Weir goes ''way'' past the MoralEventHorizon. Then it just becomes painful, because you realize it could happen to ''anyone''.
* The ending. It's a bit more subtle than the rest of the movie, but there's a dream sequence fade out followed by the real ending (which is a pull back shot of the ship) -- the doors seem to be closing on their own. It's as if there's still evil in the part of the ship that's left.
** [[spoiler:"They're with us. They're with us. '''You're with us.'''"]]
** The evil in the ship wasn't leaking through the gateway, the ship itself is alive. Just because the part of the ship capable of returning the the hell dimension is gone, is no reason why the rest wouldn't still be possessed. The more relevant question is, what happened when the ship was cut in half?
** [[SillyRabbitCynicismIsForLosers Maybe it bled to death.]]
* The set itself was nightmare fuel. The ship was designed with a kind of "techno-medieval" kind of feel, looking something like a cross between a futuristic spaceship and a gothic cathedral. When the lights are out and things are going wrong, the place looks distinctly like some kind of dungeon or torture chamber. Many of the cast members refused to stay on set longer than absolutely necessary.
