the pt had models - but many of the models would have been actual sets or partial sets in the OT. i guess the trade-off is you can build actual sets, but only so many and then you lose the diversity of locations. one of the model makers also said that the digital camera gave problems because it was too 'clean'
for vehicle models, the problem is they would have one or 2 models engulfed within hundreds, if not thousands, of cgi objects.
[sigh] have movies become 'overproduced' ? you may remember during the late 1980s, the music business focused on hit singles, slick big-budget production values and a lot of synthesized/keyboard music. then came eric claptons unplugged album and everyone was like 'wow, check this out!"
not too long after, almost every music genre (rock, pop, rap) became more stripped down and rebuilt from the ground-up.
maybe not a great analogy, but do movies need an 'unplugged'? how about the artist? its black and white and silent!! will that change things?
