Last summer ILM had competing aliens with Super 8 and Cowboys & Aliens. Now you can compare both at home on Blu-ray/DVD. In fact, Jon Favreau’s western/sci-fi mash-up arrives this week via Universal Home Ent. with an extended cut that’s 16 minutes longer. It looks and sound stunning in HD, as does Super 8. As far as Oscar, though, the J.J. Abrams homage to Steven Spielberg has the definite edge. No matter: ILM had fun with both and each offered their tech challenges. For the Daniel Craig/Harrison Ford actioner, ILM was tasked with animating a 10-foot tall, bipedal reptilian-like creature.
“We created an uber alien in evolutionary scale to make it more complicated in hierarchy,” says ILM visual effects supervisor Roger Guyett, who also oversaw onset VFX production. “We used the Legacy design as a foundation and then [VFX art director] Christian Alzmann and others developed it.
“And I thought that the irony of all this was that the aliens turn up and it could be more exaggerated for them. This is not their planet. They’re frontiersmen in a way: traveling to another place and having to deal with all the adversities of the climate. And in our case, we played up the fact that they weren’t comfortable in our world. There are flies all around them; they didn’t like the light; when they were wounded and exposed, a strange fungus grew around them.”
ILM keyframed all the animation (overseen by Marc Chu) because after doing some MoCap tests (a la Super 8), they found that it didn’t work to take the motions of a human and remap it onto the creature. “I set up an all-CG test for the studio where the cowboys were mocap,” Guyett continues. “It gave you an idea of what the aliens could do and we explored some fighting techniques (including Last of the Mohicans-style hand-to-hand) to see how they would attack a creature of that size. They have a complicated anatomy that we made organic to their behavior and in relation to their ship.”
