At the very least since I first watched Star Wars recorded off ITV onto a Betamax video tape, I’ve had a keen interest in special effects, and in films that use special effects to create unique and different worlds and beings. In this respect, though, the last twenty years or so have been something of a disillusionment: while CGI visual effects have become more and more realistic and indistinguishable from reality, they only rarely recapture one of the things I enjoyed most as a kid. See, the kind of special effects I’ve enjoyed most were never about verisimilitude, at least not first and foremost. A fantastic world is made believable and engaging by the imagination going into it more than by the number of pixels and shaders. And sure, I prefer a well-made green screen effect providing the illusion that those kids on broomsticks can really fly to a bad green screen effect aiming for the same thing and failing, but the special effects that stick most in my mind are the ones that transport me to a different, more interesting world – and that can be achieved by miniature spaceships suspended on threads you can make out if you look closely.
