3-Headed Shark Attack

3-Headed Shark Attack (2015) is an American sci-fi horror you can watch online on iFILM. Director Christopher Ray delivers a no-apologies B-movie about a mutant three-headed shark that works its way from a Pacific atoll party to a marine research station — chewing through both with equal enthusiasm.

The creature starts small: a group of friends celebrating on a remote island suddenly finds the water very unsafe. Then the shark sets its sights on the science base studying local pollution, which turns out to be tragically ironic. Danny Trejo shows up, which is the film's clearest signal about what kind of experience you signed up for.

The effects are cheap, the plot is thin, and the body count is generous — all exactly as advertised. For fans of creature-feature trash cinema, that is the whole appeal. Stream 3-Headed Shark Attack (2015) on iFILM.
