In the film, Jason Statham plays deep-sea rescue diver Jonas Taylor, who must use both brains and brawn to save the crew of a deep-sea submersible from a prehistoric 75-foot-long shark called the Megalodon. Of course, he's got a history with the beast, because, duh, it's Hollywood. 

But never mind that! The trailer looks like what might happen if the Sharknado series had a bigger budget, better writers and the baddest shark of all time. And by "baddest" we mean "most awesome." Also, maybe letting your yappy little purse dog swim in the ocean with you isn't the best idea ever.
