About CGI, action movies and ‘realism’… I know the guy who was the lead character animator on Spider-man, and I know a few other people who have done lead character animation on ‘big’ movies.
By and large, the problems referred to in this thread do not arise because of the limitations of either the animators or the tools. Good animators can depict characters walking, running and jumping in a way that is 99% realistic and credible. And the wonderful tools available these days can produce images that are 99% photo-realistic. The proof of this is that there are so many scenes where you assume you are looking at Tobey Maguire in the suit, but in fact you’re looking at the animated character. You don’t notice, because the illusion is just about perfect.
The basic problem is that it’s very hard to define what is meant by ‘realistic’ movement in something like a super-hero action flick. By definition, we want to see the hero doing things that no normal person can do, but we also want to get the sense that the normal laws of physics still apply. There is no perfectly satisfactory way to reconcile these two instincts.
Someone said it was as if the studios didn’t want to hire anyone who could advise them on physics. At least in the case of the first Sam Raimi Spider-man film, I can promise you that the makers did hire such people, and in fact used every conceivable resource to try and get Spidey’s movements and motions as ‘correct’ as they could possibly be. They had gymnasts in, and got them to perform ‘Spidey’ movements as close as they could (with harnesses and rigs helping) to film hours of reference material. They filmed real spiders every which way. They had input from physicists, dance coaches, gymnastic coaches, physical fitness instructors and many other people besides. The animators themselves went out and climbed things like steel fences and craggy walls to get a 'feel for it, and filmed their own efforts. I’ve seen lots of the reference material that was shot… it goes on and on and on like you wouldn’t believe.
At the end of the day, even for the greatest animator in the world, if you have a character who does things that no human being has ever done or ever could do, the physics aren’t going to look right ‘mentally’.
Of course, this is a coin with two sides. Think back to the Chris Reeve Superman movies. Think of the scenes towards the end of a flying sequence, after all the rear-screen stuff, where they did actually have the actor on some sort of ‘flying’ harness or rig to land him back on the sound stage. The physics always looked perfect, because there was nothing ‘trick’ about it. But on the other hand, it never really looked like a super-powerd guy flying. It always looked like an actor on some sort of flying rig.
(Apologies to anyone if this seems like a hijack, which it’s not meant to be).
