It's amazing just how much work must've been put into this. Below is the before-after comparison, the amazing part is that some things are composited via green screen and CG...
I still can't believe that the gun was entirely CG!!
This video is a great example of the importance of tracking markers. Yes, programs are now powerful enough to track without markers but that doesn't mean they don't help.
It's amazing the things we can do at home today that was nearly impossible for studios only a few years ago!!
What say you?
