Axis_mundi#Modern_Storytelling
In Avatar, an axis mundi tree is destroyed by a joint corporate-military force. The huge towering tree is brought down into total destruction & ash, on the scale of a typical Sci-Fi war movie, but with spectacular CGI. http://www.intuitor.com/moviephysics/Avatar.htm http://www.imdb.com/title/tt0499549/goofs Of course even the best movies can have a few glitches or mistakes.

Since Avatar is in 3D as well as its 2D version, more older movies will likely be offered in a 3D version.
