Cameron unveiled a new opening scene this week for an extended cut of his sci-fi blockbuster due out Nov. 16 on DVD and Blu-ray disc, the sequence offering a glimpse of life on crowded, polluted 22nd-century Earth, where city dwellers are bombarded by digital ads and wear masks for protection from the foul air.

The sequence that Cameron showed reporters depicts the dreary existence of his hero, Jake Sully (Sam Worthington), before he's invited to join the Avatar program on the distant moon Pandora. An ex-Marine now in a wheelchair, Jake lives in a tiny, seedy room and hangs around boozing it up at a bar, where he starts a fight -- but for a good cause. Jake takes on a guy who had been slapping a woman around.

Cameron said he decided to cut that opening from last year's theatrical release despite how "great that sequence of scenes is for his character, and showing how even though he's paralyzed, he's not a victim. He's still a warrior. He's a stubborn, scrappy, brawling guy, but also one with a conscience and a sense of justice."

But Cameron said audiences eventually would find that out about Jake once he gets into action among the native Na'vi on Pandora. He said he dropped the opening on Earth to step up the pacing and land viewers more quickly on Pandora, where Jake falls for Na'vi warrior Neytiri (Zoe Saldana).

Isn't the movie itself commentary enough about the state of the world, how we treat our natural resources, but more importantly how we treat OURSELVES! pity we feel the need for Cameron to hand hold us through the desolutness of life.
