What with The Chronicles of Narnia: The Voyage of the Dawn Treader involving, as the name suggests, being aboard ship quite often, it's probably no surprise to hear that production on the third Narnia film has moved from New Zealand to Mexico - specifically to the Baja production site where Titanic once filmed.
The plan is to base the entire production in Baja, except for a few location shots that have already been planned for Australia. There's no word yet on whether there'll be a quick trip to New Zealand as well for establishing shots.
The producers are denying that this move has anything to do with the fact that Prince Caspian has so far grossed less than half the take of The Lion, The Witch and The Wardrobe, and in fairness it certainly does have more to do with the need for a great big water tank.
With Michael Apted set up to direct it, and the young Pevensies and Ben Barnes (as Caspian) signed on for more adventures, filming is due to start in January 2009 for release in May 2010.
