That's just like real farming. Spend all your money planting a crop, make it all back...
That whole series of how they made Interstellar is fascinating to watch. So many aspects of the filmmaking process that could have been achieved in post was actually created in camera. Nolan is an incredible director IMO.
Was the tesseract expensive or were they able to recoup their cost on that too?
It's cool they had a designated plot specifically for shooting. I know farmers that would cringe seeing that truck zoom through a productive corn field, paid or not.
I wonder if when the director told the production crew "we need a great plot", he was talking about storylines?
