Here’s what you need to know.  James Cameron’s epic Avatar is coming to back to theatres for a limited two week run from August 27 to September 10.  It will only be shown in IMAX 3D theatres and will include “eight minutes of additional, never before seen footage.”  So, if you haven’t seen the highest grossing movie of all time yet this is your chance to catch it the way it was meant to be seen–in IMAX 3D.  And if you have seen the movie and enjoyed it the first time around, you might be interested in kicking back a second time to catch the new bits of footage.  The movie looks fantastic in IMAX 3D because it was shot for that particular medium.  If you purchased the movie on DVD or Blu-ray and haven’t see it yet, hold off on that until you’ve seen it in 3D.  Trust me, it’s worth it.
