This enjoyably ridiculous action thriller from director Renny Harlin features a plot where sharks are made bigger and stronger so their brains can be harvested for a cure to Alzheimer's disease. Because you know...science. But this process has the side effect of producing really intelligent sharks, who decide they don't like being used as guinea pigs and plot their escape. And with a setup this dumb, you know you're in for a good time at the movies. Samuel L. Jackson plays the businessman bankrolling this research who flies down to the isolated sea lab to see how it's going. Pretty soon the cr*p hits the fan, the sharks escape and the lab starts sinking. At a particularly low moment for the survivors Jackson launches into an impassioned speech to rally their shattered spirits. They stare enraptured as his words stir them back to life. With this total badass leading them of course they can make it. Then a massive shark dives out of the pool behind and eats him. The combination of the film killing its biggest star in the middle of his rousing "We're going to survive this!" speech makes for a moment that's both shocking and hilarious, and cannily sets up that everyone is on the menu.
