Star Wars is known for its spectacular special effects; the original trilogy has avoided aging as radically as the prequel trilogy because it used models rather than CGI. CGI has its place in films; enhance an explosion; create terrifying monsters; construct the unbuildable. But it is not necessary to make every single detail through a computer. The clone troopers of the prequels (who would become the storm-troopers of the originals) were supposedly all made with CGI; watch Episode III and you will see that there is a clearly computer generated tint to each and every one of them. This makes sense as they are meant to be clones, but it cannot be that hard to find a legion of men keen to step into a storm-trooper costume; reality trumps CGI-a lesson we have all learnt the hard way thanks to the prequel trilogy. JJ Abram's has stated he would rather avoid CGI effects if possible; the reboot of Star Trek had amazing effects through this, although the penchant he has for lens flares can become rather irritating. I doubt that the new Star Wars will bare a major resemblance to Star Trek as such a crossover would provoke fan-fury, but the wariness of Abrams to use CGI could be a good thing, especially when we consider how deep George Lucas fell in love with the new effects.
