Recently I’ve been lecturing in visual effects at the SAE Institute in Islington. Towards the end of the module, where we are now, we look at the FX requirements of Dark Side of the Earth and the students have to come up with ways of achieving them. This week one guy went all Tim Burton on a wooden robot character – nothing wrong with that – and suggested it was controlled by a legion of woodworms that lived inside it. Not appropriate for my film, but a fascinating idea.
