People coming in from the outside, as well as employees, look at the process and say, “you know, if you would just get the story right—just write the script and get it right the first time, before you make the film—it will be much easier and cheaper to make.” And they’re absolutely right. It is, however, irrelevant because even if you’re really good, your first pass or guess at what the film should be will only get you to the B level. You can inexpensively make a B-level film. In fact, because the barriers to entry into this field now are quite low, you can get to B easily.
If you want to get to A, then you have to make changes in response to the problems revealed in your first attempt and then the second attempt, et cetera. Think of building a house. The cheapest way to build it is to draw up the plan for the house and then build to those plans. But if you’ve ever been through this process, then you know that as the building takes shape, you say, “what was I thinking? This doesn’t work at all.” Looking at plans is not the same thing as seeing them realized. Most people who have gone through this say you have to have some extra money because it’s going to cost more than you think. And the biggest reason it costs more than you think is that along the way, you realize something you didn’t know when you started.
