MSN.com just got their hands on a second exclusive Avatar clip. Avatar is the story of an ex-Marine who finds himself thrust into hostilities on an alien planet filled with exotic life forms. As an Avatar, a human mind in an alien body, he finds himself torn between two worlds, in a desperate fight for his own survival and that of the indigenous people.

The film was first conceived by Cameron 14 years ago, when the means to realize his vision did not yet exist. Now, after four years of actual production work, Avatar delivers a fully immersive cinematic experience of a new kind, where the revolutionary technology invented to make the film, disappears into the emotion of the characters and the sweep of the story.

Avatar hits theaters on December 18.
