Do I LOOK like I'm in need of a psychological evaluation?

Peter Krill is the secondary antagonist in the 1992 film Under Siege.

He was portrayed by Gary Busey...who also played the roles of Jack Joshua in Lethal Weapon, Ty Moncrief in Drop Zone, and "Doc" Hawkins in Surviving the Game.


Peter Krill is the executive officer on board the USS Missouri. His most recent performance review by his captain states that he shows signs of mental instability and is unnecessarily hostile to his men, and indeed later proves he is perfectly content to drown his crewmen. Krill loathes Casey Ryback and seems insanely jealous of the Captain's high esteem for the lowly cook. He is quickly revealed to be in league with rogue CIA operative William Strannix.

Krill is generally mean and contemptuous to everyone he speaks to. In the Captain's presence, however, he is considerably more respectful and nervous.


Because of his status as the Missouri's XO, Krill is the reason Strannix is able to board and take over the ship, and to seize control of its nuclear missile defenses. Krill accomplishes this by pretending to throw a surprise birthday party for the Captain, bringing Strannix and his crew aboard disguised as entertainers and caterers. When Casey Ryback refuses Krill's orders to clear out of the kitchen, he provokes Ryback into assaulting him, then imprisons the cook in the meat locker (since nobody goes to the brig without the Captain's approval). When Strannix and his men take over the ship, Krill gleefully murders the Captain himself. In the heat of the takeover, Krill entirely forgets about Ryback's imprisonment, inadvertently leading to Ryback's escape and subsequent guerrilla war against the terrorist team.

As Strannix and Krill prepare to offload the Missouri's nukes, Ryback escapes and uses sabotage and guerrilla tactics on the terrorists to sow chaos and disorder, thinning out their numbers, and ruin their escape plans. As losses mount on Strannix and Krill's sides, to draw Ryback out into the open Krill seals his crew in the forecastle and turns on the fire sprinklers, knowing that Ryback will try to save them from drowning.

Krill seconds before his demise.

When the nukes are finally loaded onto Strannix's stolen submarine after overcoming much difficulties, Ryback sabotages the submarine by ruining its bow plane, rendering it unable to submerge. Also by this time, Ryback has freed some of the captured crew and taken control of the Missouri's naval cannons. With the crew's help, Ryback uses the cannons to blow up the sub before it has chance to submerge. Realizing Ryback's intention, Krill frantically orders sub crew to fix the jammed bow plane and boards the sub to make his escape after first salvo shot missed. Just as bow plane was fixed, Ryback and his crew fires second salvo, and this time it was a hit; the shell from USS Missouri penetrates into the submarine, blowing it up, killing everyone on board including Krill.
