Sharktopus is a 2010 SyFy original horror/science fiction film produced by Roger Corman, directed by Declan O'Brien, and starring Eric Roberts. It is the first film in the "Sharktopus" franchise.
The U.S. Navy commissions a group known as "Blue Water" to genetically engineer a half-shark, half-octopus for combat. During a demonstration by Dr. Nathan Sands (Eric Roberts) where the creature is attacking drug traffickers off of Santa Monica, the creature called Sharktopus escapes the control of its creators and makes its way to Puerto Vallarta. Hunted by Blue Water and a television crew, Sharktopus attacks numerous beach-goers including a woman on the beach with a metal detector as a man walking on the beach sees that and after she is taken, he leans over and picks up a old coin and bites it to see if it is real. Then Dr. Sands is killed by the creature's sharp tentacles. The news woman Stacy, and her cameraman Bones are also killed. Sharktopus is eventually defeated by detonating explosives embedded in its brain.
