Why is there so little imagination in movie “special effects”? “Part of the problem, I think, is that technicians get excited about techniques that stretch possibilities, for strictly technical, not to say geeky, reasons. We could never do that before, so it must be cool. Trouble is, what looks cool to the person who stretched the technique doesn’t necessarily look cool to someone who doesn’t realize that the technique has been stretched. Whenever a director comes along with a really striking new look, a striking new way to imagine the future, we see the same look replicated over the next couple of years, until someone comes up with another look.”
