This is the second of in a series of posts about James Cameron's new film Avatar.
As Luke Skywalker might say, finding fault with the science in science fiction films is about as challenging as bull's-eying womp rats from a T-16 back on Tatooine.
Yes, every now and then a science fiction film takes as a central premise an intriguing theory and expands upon it using plausible extrapolations of current technology and scientific knowledge. The movie Contact (1997) and its treatment of the search for and discovery of intelligent extraterrestrial life shines in this regard.
More often, the science of a science fiction film serves as a device used to transport a conventional story to a dramatically different setting, where, stripped of the distractions of our everyday world, its themes can be amplified and so stand out in starker relief. This kind of borrowing is as old as the visionary 1927 silent science fiction masterwork Metropolis and its "scenes from the class struggle", set in a near-future urban dystopia.
It would be fair to say that Avatar falls squarely, and respectably, into this second category. Its narrative is so similar to Kevin Costner's 1990 Academy-Award winning film, that I began to refer to it as "Dances with Avatars" after only seeing the theatrical trailer. Director James Cameron re-situates this story of the American West, itself many times retold, to the Eden-like world of Pandora, where the encounter of a rapacious, imperialistic human culture with a noble indigenous people, living in harmony with their ecosystem, unfolds, in part, as a work of contemporary political commentary and, in part as cautionary environmental tale.
Science enters the picture, so to speak, in several ways.
Cameron has gone to some length in the early scenes to fashion a realistic spacecraft to be used to transport his human characters to Pandora, a moon orbiting a Jupiter-like gas giant planet of a presumably nearby star. The passengers, themselves, have been placed into some sort of cryogenic sleep, the better to endure the apparently lengthy voyage. Echoes of the technologies of 2001: A Space Odyssey (1968) are quite vivid here, and they remind us how diligently Stanley Kubrick labored - 40 years ago - to imagine realistic long-duration space travel. It makes the scientifically-minded among us wistful for the days before the invention of warp drive.
The Macguffin that drives the human plunder of Pandora is a mineral named - in the best self-mocking science fiction tradition - unobtanium. We are told little about other than that it is extraordinarily valuable, and that its mother lode lies directly beneath the arboreal habitat that is the hub of the community of the tall, blue-skinned, anthropoid natives called the Na'vi.
Although it would be hardly sensible to send a ship into deep space to obtain a "precious" resource that - given the technological advances that would make such a mission feasible - could be manufactured much more cost-effectively here on planet earth, this plot device has become such a fixture of the science fiction canon that it was long ago exempted from being considered a threat to the suspension of disbelief.
Oddly enough, Avatar's significance not only as a science fiction film but as a science film has little to do with technological gimmicks, like interstellar travel and a rare superconducting mineral, and everything to do with the unprecedented detail with which Cameron has crafted the biology - both flora and fauna - of the hypothetical world which serves as the setting for his film.
As the credits rolled at the end of Avatar I turned to my friend Carol Potter, a high school biology teacher in Gwinnett County, Georgia, a state not known for holding Darwin in particularly high regard, and said, "if it weren't for all the tall, lithe, athletic, semi-nude blue bodies, this movie could make a great addition to your curriculum on the theory of evolution." *
By that comment I did not mean to endorse Cameron's wide-eyed vision of an alien biosphere so interconnected that it behaves as though it were a single organism (in accordance with the speculative and widely-criticized Gaia hypothesis), but to point out that the director had sketched the outline of an intriguing version of an alternative Galápagos, a world in which familiar ecological niches are occupied by strange and exotic creatures related, mostly, by common descent. **
Unfortunately, the scientists of Avatar - exoanthropologists, one might call them - are consigned to secondary roles. What a difference it would have made had James Cameron seized the opportunity - in the very year that marked the 200th anniversary of Charles Darwin's birth and the 150th anniversary of the publication of his On the Origin of Species - to position a scientist-explorer, and not a disillusioned imperial soldier, front and center as the hero of his movie. With more artistic daring this recycled tale of thwarted neocolonial conquest could have been replaced by a bold re-imagining of Darwin's Voyage of the Beagle. Avatar could have taken its place as not only a technical tour de force of film production but also, by making a scientific adventure the center of its story, a work of science fiction of the highest order.
* Depiction of the naked human form, I imagine, is even less welcome in Georgia classrooms than the notion that we, as a species, are descended from apes.
** I say "mostly" here, because the humanoid Na'vi have 2 arms and 2 legs, unlike the 6-limbed creatures with whom they share Pandora. This concession to commercial necessity - that the Na'vi appeal to general audiences - is best captured by a quote from an interview with James Cameron in Playboy in which he says of the native heroine Neytiri that he knew from the start, “she’s got to have tits.”
