The finished short is pretty neat as well. It's amazing how a 0 gopro can do realistically what I'm only assuming were ,000,000 shots in the new Spiderman could not.
I bet those shots in Spiderman weren't nearly as expensive as you think. CGI has matured to the point where it's being used because it's cheaper than practical special effects and crews for location shooting as much as anything else. The vast majority of the budget in modern huge-budget blockbusters goes to hiring a couple of name stars and marketing, because shooting in front of a green screen isn't all that expensive and sets in that sort of thing are mostly CGI.
