I've been working on putting together the business plan, budget, and schedule for an upcoming film project and I've run into a real road block when it comes to acquiring data to use to attempt to calculate a ROI.
I have the book that Jeremy Juuso wrote called "Getting the Money" but though it appears to have been useful once upon a time, it's now a bit out of date. When Gracenote bough Baseline Studio Systems in 2016, they greatly increased the price of data. Variety sells similarly priced data and the information available through Box Office Mojo and The Numbers does not appear to be as complete.
At this point, with data being so expensive for new filmmakers, what is the opinion on the necessity of calculating an ROI as part of a business plan? I'd love to be able to, but Gracenote has increased the barrier to that data in a way that is significant. Anyone have any tips?
