no eyewitness accounts from the original test audience can be found.
The Event Horizon itself isn't so bad anymoreWhen the side of the ship that contained the gateway was destroyed, it got rid of most of the evil on the ship. The final hallucination scene and the door closing were the result of residual hellish energy residing in the crew quarters.
The "realm" that the Event Horizon traveled to was The AbyssWeir defined it as a dimension of "Pure chaos and evil"
The Movie is set in its own self-contained universe independent of other franchises and properties unless officially stated otherwise by the parent company.Bet you didn't think of that.
The film is a Broad Strokes-sequel to 2001: A Space Odyssey
Weir is a ScelestusHe's being manipulated by an abyssal being. It was him that activated the portal remotely using magic. An abyssal entity is the thing that possessed the Event Horizon. The film takes place in the far future of the New World of Darkness.
Weir is a Nephandus.The crew of the Louis and Clark are sleepers, and Weir was orginally a Void Engineer sent by the Technocracy to check out the Event Horizon after a trip through the Umbra. Unfortunately, the mini-singularity he designed proved to be an inadvertant Caul. Normal sleepers going through it just get regularly mind raped. Weir, going in on the other hand, makes him rethink his allegiances somewhat...
The Event Horizon found a passageway directly into Malfeas, possibly into the Black Spiral Labyrinth itself.The Event Horizon stumbled upon a Deep Umbral passageway into the Black Spiral Labyrinth, which would explain the mental and spiritual deterioration of its crewmembers, as well as Weir's physical changes.
The portal released Pennywise from the outer voidPennywise didn't die. Rather, it faked it's own death and lived on into the distant future. Alternatively, the supernatural force possessing the ship is another one of Pennywise's species. It also seems to feed on violence and fear, and uses hallucinations to snare its prey.
Alternative idea. All of the "supernatural" weirdness was, pure hallucination, brought about by gravitational distortions rippling through the ship and playing merry hob with the crews' neurons. Traveling through hyperspace isn't an actual alternate dimension that resembles Dante's hell; it just drives you completely crazy.
The lost Event Horizon and Lewis and Clark crewmen became Reavers.
Dr. Weir is a Cenobite.This is actually a pretty widespread assumption. Dr. Weir even becomes a Cenobite for the same reasons others do: deep emotional pain. And the "Hell dimension" features a ton of Clive Barker-like leather, barbs, and so forth. Weir has the same Body Horror fascination, too.
Event Horizon is set in the Star Trek universe.In the Star Trek: Voyager episode "Random Thoughts", we get to see all the violent thoughts in Tuvok's mind. Among them are three images from Event Horizon. Either he saw the movie once and it somehow made an impression on him or the events of the movie happened In Universe, one of the survivors got mind melded by a Vulcan doctor at some point after First Contact, and Tuvok mind melded with either that Vulcan doctor or another Vulcan who mind melded with that Vulcan doctor and the images got transferred during the meldings.
Event Horizon is based in the same universe as DoomBoth feature a transport system that transports though hell and in both cases something comes though from the other side.
Event Horizon takes place in the distant, distant future of Sauna's universeBoth evil forces come from a place of darkness. Both of them seem to feed off negative emotion. Both lure their victims in with visions. Both seem to be able to possess people with corruption. Clearly the Sauna's Eldritch Abomination simply has found a new form to mess around in... The End... Or Is It? ending with his crew. His greatest fear was something happening to his crew - what would Mind Screw him most as he lay dying? The idea that despite his Heroic Sacrifice that his crew NEVER GOT AWAY.
The two ships mentioned as missing in the beginning of the film were sent out after the Event Horizon.Remember when Miller mentions that the last two ships that "went out this far never came back"? How much do you want to bet they were sent out after the Event Horizon? And they were likely rescue ships just like the crew of the Lewis and Clark, hence the fake "rescue" scene near the end.
The other half of the Event Horizon is also going to that place where we won't need eyes.Hence the weird "iris" effect at the end.
Event Horizon is the prequel to Disney's The Black HoleIn both films, the black hole leads to Hell.
Hyperspace is a huge colony of boggarts.It causes you to see your worst traumas and fears, right? So if the crew had all been wizards, they simply would have needed to say "Riddikulus" and it would have changed into something funny (in the case of Weir, for example, it would have changed into a guy in a Paper-Thin Disguise as his wife.) horrifying Slasher Smile. Both inhabiit dimesions of pain and horror.
The directors of this movie are constantly headdesking at seeing all the "It's clearly Warhammer 40k/Doom!They wanted to make their own universe... and now it seems any universe where Hyper Space Is A Scary Place clearly must be a part of Doom or Warhammer 40k or that it's clearly a Warhammer game. How would you feel?
Weir bankrolled this trip himself.The ship didn't send out a distress call picked up by Earth - the ship called Weir. Weir paid for the Lewis and Clarke and was lying that it was for official business and using his government connections.
Miller is in Heaven.If Hell really does exist in the movie, it's a fair assumption that Heaven does as well. Given that Miller performed the Ultimate Sacrifice to save what was left of his crew, passing through Hyperspace probably led him to Heaven rather than Hell, while Weir, who may or may not be dead by that point, went to hell. It's possible that Hyperspace acts as a judge that decides where you end up.
