Air Force One is certainly not a new film but buying it in its Blu-ray edition will most definitely be a new viewing experience for you.  I do have the original DVD release, which I had always thought was pretty good, however, on Blu-ray you will find yourself on the seat of your pants almost from the beginning.  In the first takeover scene on Air Force One, the bullets go flying literally all around you. The lossless audio is just outstanding.  Too many films skimp on proper audio production but not on this disc.  There is extensive use of all five channels from front to back, side to side and diagnally through the sound stage.
