There are times when movie companies even use toys to plot out a sceen. Imagine if that type of footage were to surface. Many of these people acting like the comic book guy from the Simpsons would kill over. So yeah if it was fake, the person who went to these lengths needs to get a life since obviously a ton of time was put into it. They should invest time in trying to get a job at ILM instead of faking footage from them. I highly doubt this to be fake just based on the shear amount of time it would take to fake this. Even if it's not for the movie, it's footage to something.
