From watching that we have surely just seen the end of thousands of more jobs, killed off by technology. All those extras, set designers, make up artists, costume designers, grips, engineers, even lighting and cameramen that normally need to be hired, taken to the location, accommodated, fed and otherwise looked after, no longer necessary.I'm not 100% sure about that.
I think CGI is ineffective for foreground shots involving humans and close up stuff. Filming real people/sets and painting in the backgrounds can be very effective.
Here are four videos I posted elsewhere about the making of Boardwalk Empire (to me, one of the best TV series ever made). The 4 minute ones are probably the best as they are made as promos by the digital FX company Brainstorm Digital
They make it look very easy!
Short: 4 minutes.
Medium: 8 minutes;
Long: 90 minutes:
A small crew and cast to film the up close work and then leave it to the blokes in the graphics studios to do the rest at a fraction of the cost.
