Captain Miller is the captain of the search and rescue vessel, The Lewis and Clark. Miller is shown to be very loyal to both the mission and even more so his crew. Not much is known about him other than he is American and was once on a vessel called The Goliath which caught fire. He was forced to leave one of his men behind, Which the Event Horizon uses to torture him.
Captian Miller doesn't survive. He is sucked into a black hole along with Dr. Weir.
Captain Miller of the Lewis and Clark – along with second in command Lieutenant Starck, pilot Smith, medical technician Peters, engineer Ensign Justin, Doctor D.J., and rescue technician Cooper are also joined by the Dr. William Weir. Dr. Weir, who designed the Event Horizon, briefs the crew on the ship's experimental gravity drive. The drive generates an artificial black hole and uses it to bridge two points in spacetime, reducing travel time over astronomical distances.
Upon boarding the Event Horizon, the crew finds evidence of a massacre. As they search for survivors, the ship's gravity drive automatically activates. Justin is briefly pulled into the resulting portal. The activation also causes a shock wave that damages the Lewis and Clark, forcing the entire crew to board the Event Horizon. After Justin is pulled out, he is in a catatonic state, terrified by what he saw on the other side. He attempts suicide, forcing the crew to place him in stasis.
The team begin to experience hallucinations corresponding to their fears and regrets: Miller sees Corrick, a subordinate he was forced to abandon to his death; Peters sees her son with his legs covered in bloody lesions; and Weir sees his late wife, with missing eyes, urging him to join her. The crew soon discover a video log of the Event Horizon's crew going insane and mutilating each other. The video log ends with a shot of the Event Horizon's captain, who has apparently gouged out his own eyes, holding them up to the camera and saying in Latin, "liberate tuteme ex inferis" ("save yourself from Hell"). Miller and D.J. deduce that the ship's gravity drive opened a gateway into a dimension outside the known universe. Starck theorizes that the Event Horizon has somehow become a sentient being which is tormenting its occupants in an attempt to kill them or lure them back through the portal.
Miller decides to destroy the Event Horizon. Peters is lured to her death by a hallucination of her son. Weir, who has gouged his own eyes out & is now possessed by the evil presence, uses an explosive device to destroy the Lewis and Clark. The explosion kills Smith and blasts Cooper off into space. Weir kills D.J. by vivisecting him and corners Starck on the bridge. Miller confronts Weir, who overpowers him and initiates a 10-minute countdown until the Event Horizon will return to the other dimension.
Cooper, having used his space suit's oxygen supply to propel himself back to the ship, appears at the bridge window. Weir shoots at him and is pulled into space by the ensuing decompression. Miller, Starck, and Cooper survive and manage to seal off the ship's bridge. With their own ship destroyed, Miller plans to split the Event Horizon in two and use the forward section of the ship as a lifeboat. He is attacked by manifestations of Corrick and a resurrected Weir. Miller fights them off and detonates the explosives, sacrificing himself.
- Miller might've died in either the Explosion or is in 'hell'
- His American flag patch has 55 stars instead of 50
- he is very eager to live up to his title as captain
