Questions on Karst

My questions for Karst is not actually about the film’s subject matter but on the process of the film

How was this project planned from start to finish?

What resources were needed to create this film? were there sponsors for this?

And most importantly

How does this film important to us in terms of project planning? What makes it a good example to study? Is it the film’s subject matter or do we need to speculate on how this film was made
