No, he has a good point. The actual budget is far in excess of $82,000. $82,000 is just how much liquid cash they spent. The opportunity cost of the entire film is, as he stated, somewhere around $1 million or something.
Consider this. What if the people who volunteered their time instead just donated money?
If those people gave $1 million, which was then spent to hire other people to do what those people volunteered to do, the end result would be the exact same.
You'd have $82,000 left over to spend on the set, etc, having spent that $1 million dollars on acting, labor, etc.
Would the cost of THAT film be $82,000? No, it cost $1,082,000.
So because this money was donated, you're not counting it?
Or because the volunteers immideately "spent" the money on themselves, it doesn't count?
Its economics.
