I didn't say that film making isn't rocket science, I said identifying the business alternatives is not rocket science. These are approaches that have been used successfully in many industries with varying complexity (packaged foods, chemicals, high tech electronics). For example, Foxconn manufactures the iPhone as well as many other high tech products for other companies.
That doesn't mean that it CAN work for film production. If "Formulas do NOT move between plants gracefully" that is certainly a deterrent. Whether it's insurmountable (given the potential returns) I don't know.
