THE ULTIMATE PREDATOR JUST GOT SMARTER. From Renny Harlin, maximalist director of Die Hard II, Cliffhanger and The Long Kiss Goodnight, comes Deep Blue Sea, a shark-infested action-thriller where everyone is on the menu. At an isolated research facility in the middle of the ocean, a team of scientists, led by Susan McAlester (Saffron Burrows), are working on a cure for Alzheimer's by genetically altering the brains of sharks. When a shark escapes and attacks a pleasure boat, the company sponsoring the research threatens to pull its funding and sends corporate executive Russell Franklin (Samuel L. Jackson) to investigate. McAlester has just 48 hours to prove the value of her work, but her experiments have made the sharks smarter. No longer happy to be injected, prodded, and caged, they begin to turn the tables.
