Event Horizon ending explained (spoilers)

[Faisal Zahid]

In the end, it turns out that the ship has, indeed, been to hell (or a dimension that resembles it), and that Dr. Weir, the scientist who created the ship goes completely insane and is now under the ships' control (or the entity/s occupying it). When the crew try to leave he blows up their ship with the pilot, onboard (who refused to leave but rather tried to find the bomb). Crewmen who oppose him also die, with one having his chest ripped open then left strung up by wires stuck into his slashed to shreds torso flesh. They eventually kill him, but he is reincarnated by the hellish powers of the ship. In the end, Captain Miller distracts Weir by engaging him in a smackdown while Starck, Cooper and Justin are able to blow up the part of the ship with the black hole (along with Weir and Miller). Starck, Cooper and Justin survive ~ all the rest of the crew members perish. But Starck has a vision of Dr. Weir being one of the men coming to rescue the survivors...
