James Cameron's Avatar at the BFI IMAX.
Starring the rather lovely Sam Worthington (as Jake) it tells the story of him 'becoming' an Avatar and using it to interact with the Na'vi - a tall blue computer-generated race who inhabit the strange blue computer-generated planet of Pandora. Initially Jake's working for the evil RDA trying to exploit the ridiculously named mineral Unobtainium but then he inevitably goes native.
Ok, so the plot is thin as paper and the film way, way too long but it looks great.
Reminded me a bit of Titan A.E.
A sequel or two in the offing? As Cameron said last week, "Yes, there'll be another."
