The OP asked if he should consider the Market / distribution channel before completion of film
APE responded, in so many words, that if the filmmaker is considering distribution channels other than "self" or youtube/vimeo pro, s/he should consider the technical thresholds / limitations of the distributor. That's a perfectly reasonable answer. The Weinstein Co will not want to be associated with my technically flawed product even if they like my story. Their QC will disqualify my movie from consideration if they cannot fix the problems in my film. That's perfectly sensible, and APE was pointing out this consideration, as most "independent" filmmakers overlook these things.
It's fantastic, Gorilla, that you've been involved with product launches that apparently were launched without market and legal considerations, and in one instance you mention US$ 50mm was authorized in R&D spending without any market analysis. That is just difficult to believe. If it's true, it's negligence. You're asserting that some CEO would authorize 50mm in spending without at minimum, looking at a basic comparables analysis? What does it take? Just get a subscription to Thomson Research and have an underling do a summary of the already existing market research? Companies do it all the time. But according to you, and your 20+ years of experience, this is too much. Everybody is just driving blind and lucking out.
Unlike APE, I don't have any film industry experience. But I can follow APE's logic. I'm not sure what you are suggesting Gorilla, that a filmmaker should do. S/he should just make a movie and then throw it out there? What is the plan? What are the considerations, technical or market or otherwise? Or are we just supposed to go with your 20+ years of experience and leave it to the wind, because that's what all the successful billionaire CEOs do? I'm not trying to be facetious. But your commentary does not provide direction.
