A lot of the Star Wars artwork and media is in a travelling exhibition, went to see it a few years ago - really though if you compare the early models with the new stuff, model makers got damn lazy damn quickly.
Like the pod race, the massive building with all the people is made from wood, covered in glue, dipped in sand - then hundreds of painted cotton buds make up the crowd - with some mini action figures (the kind you'd get in a real cheap toy). Now that practically everything is computer generated they don't put any care into their work.
Now if you check out the speeder bike, or the milenium falcon models they're works of art!, the most detailed models I've ever seen. Seriously the big wedge ships have sides made from stacked jigsaw pieces, so very cheap, but the important thing is it must have taken ages, and the detailing they add was intricate as hell, laser damage and scraped metal done with real care.
The best bit is when that guy says 'I haven't even been on set yet!' - Lucas must be the least popular director ever, how can anyone polish 3 diamonds and end up with 3 turds instead
