This strange mixture of good production values, bad acting, decent special effects and a truly messy screenplay will keep you hooked to the screen, primarily because you'll probably be saying 'I can't believe it!'.A hundred years in the future the crew of the submarine Nautilus travel back in time to our present day in order to stop a power company that is drilling into the Earth's mantle. They believe that this will cause a series of natural disasters that will nearly destroy mankind. We're shown what this future world looks like in the opening credits, with collapsed buildings, fire and desolation.The drill is located on an ocean oil rig, which you'd think the Nautilus would have no problem stopping. Instead, there's a lot of talk-and the destruction of an armed ship. The captain of the Nautilus wants to show two of the scientists what will happen if they drill-and this is replayed on the front screens of the ships. But once the captain thinks he has changed history he checks the timeline and everything has remained the same. It turns out that the Nautilus is responsible for the terrible future world.First, why is it they have a submarine go back in time? Secondly, if they can go back in time you would think they wouldn't appear hours before the whole cataclysmic event is supposed to happen. It shouldn't be a race against time-after all, they have all the time in the world if they have a time machine! One of the main characters is this annoying mercenary guy with an Australian accent who is hired as the oil rig's chief of security. Think of all the one-liners he could say and he says them. After the first hour the movie gets a bit redundant and ends exactly how you think it would end.
