Jim Whitlock was the fish doctor in the 1999 film Deep Blue Sea.

He was portrayed by Stellan Skarsgard.


At Aquatica, a remote former submarine refueling facility converted into a laboratory, a team of scientists is searching for a cure for Alzheimer's disease. Unknown to the other scientists, Dr. Susan McAlester, with Whitlock's help, violates a code of ethics and genetically engineers three Mako sharks to increase their brain capacity so their brain tissue can be harvested as a cure for Alzheimer's, but this causes the side effects to make the sharks smarter, faster, and more dangerous.

After one of the sharks escapes and attacks a boat full of teenagers, Aquatica's financial backers send corporate executive Russell Franklin to investigate the facility. To prove that the research is working, the team manages to remove brain tissue from the largest shark. While examining it, Dr. Whitlock, one of the researchers, is attacked by the shark and his arm is bitten off.

Brenda Kerns, the tower's operator, calls a helicopter to evacuate Jim but a strong hurricane causes the helicopter to lose control and crashes into the tower, killing Brenda and the pilots. One of the sharks uses Jim's body as a battering ram to smash an underwater window, flooding the research facility and freeing the other sharks.


Susan then confesses to the others that she genetically altered the sharks with Whitlock. They later find that the sharks intended to flood the facility to kill the researchers so they could escape into the open ocean and breed.

When Carter Blake swims back to the research room, only to run into Jim's drowned corpse, still strapped to the gurney. Blake swims back to the surface, screaming in terror.
