James Cameron and a team of marine and history experts (and Bill Paxton) send his specially created, state of the art diving cameras down to the wreck of the Titanic. The results on Imax, are rather predictably, spectacular.
So how exactly do you follow the highest grossing film of all time?
Well, if you're James Cameron, you take your sweet time and finally revisit your biggest hit, this time in 3-D.
The director's first foray into the world of Imax goes deep down to the bowels of the Titanic with an awed Bill Paxton ("Look, it's the ship's hull!"), promising to explore previously unseen aspects of the wreck. The 3-D gimmick undoubtedly adds to the enjoyment - the huge crashing waves and the Titanic looming out of the murky depths are breathtaking - but after the novelty begins to wear off, it becomes apparent that the whole concept of searching a 90 year-old wreck is actually quite dull.
Despite Paxton's whooping every time a new artefact comes on screen, it's hard to be constantly excited about watching a bunch of rusty, decayed junk - historic and three-dimensional though it may be.
