I visited an IMAX in 3-D experience when I saw the movie. It was one of the coldest days ever in San Antonio, Texas! That did not stop an almost sell out crowd being there. The movie began at 10:45 p.m. and was over at 1:30 a.m.. I did not see anyone sleeping. Even the under 10 year old sitting on my left side was awake and enjoying every minute of the film. I highly recommend this film to everyone to see!
