I saw this video last week and found again today. It was funny last week and it still holds up a whopping 8 days later.
Seriously though.....this is just another example of how great the digital effects are becoming. You don't have to be a major motion picture studio with a million-dollar budget in order to get these kinds of effects.
Just think.....if George Lucas had these tools back in the 70's maybe we would have only gotten one version of Star Wars instead of however many we have now. Of course he still would have re-cut things to make Greedo shoot first, but the other stuff would've been in the original release.
