Actually your explanations include 3 different/contradictory claims:
-
You “need money to pay for the movie”, so without the funding the movie can not be made.
-
“In short, the movie will be finished eventually”, means the movie gets finished no matter what, so if you get the funding or not does not really matter, apart from the required time aspect.
-
You “work 8-10 hours a day just to earn money for the movie”, so you have a full-time income available just for the movie production alone.
How much of your income you spend on your hobby (making the movie) is up to you, but I doubt you will find “investors” as your wrote on Jan 2023, because they want to have a return/profit for giving you money.
Also you misunderstood what I meant by “you can release the film without any cost”. I was referring to the RELEASE only, as you can put it up for free on Youtube and many other platforms without any cost. You on the other hand wrote “the costs involved (in making the movie)…thinking it’s costless is just naive” refering to the production instead of the releasing.
