I watched the Revolutions at the GV IMAX, pretty cool. I was like 5 rows away from the screen, a bit too close. ;p
I watched Reloaded at an Imax theatre in the States, it's pretty cool as well. But I don't remember being that close.
It's also more "wide screen".
The detail is amazing.....
Heard/read somewhere Return of the King will be on IMAX, not sure if it will be launched here.
