As Kevin Smith might say, Finish it, sir.
It’s true and the sooner a writer breaks through that wall and gets to the point where they can see their flaws, the better.
I'm lazy and hate editing, so I've suffered the wrath of many a critic, many a seasoned reader, and my own self-loathing when I reread my own work. Ugh. Double ugh. Who says, "Ugh?"
Those are some obvious differences.
Or maybe you decide you like your story just fine, you like your script just fine and you want to make the film yourself! Glutton for punishment.
When Clive Barker decided to make Hellraiser, he went to the library for books on directing because he'd never done it before. To his chagrin, those books were checked out...but it didn't stop him from creating an iconic horror film.
And then you can’t find the perfect location and the budget won’t allow you to build sets to spec, so you tweak some more. You had written fifteen characters but the budget, schedule, and your group of friends and local film community will only support eight, so you tweak. And maybe ten other things aren’t going to work due to ten other limitations, and so you tweak. It’s not giving up on your vision as much as it is being flexible. Flexibility is key--so important. With a novel, rigid is doable...with a film, it may just be a death sentence.
On a film, you are part of a family—hopefully a family that support your vision. They will be dysfunctional and need guidance. You will be dysfunctional and need guidance, but hey--It’s no longer lonely. Your phone is blowing up and your Facebook messenger is blowing up and your skull is throbbing from all the possibilities and the headaches, albeit good headaches. The creativity is flowing...lots of moving parts.
It is a flipping miracle that any feature film gets made. A miracle. It’s no wonder Hollywood relies so heavily on formula and remakes and sequels—they are safe.
My little bit of advice won't get your film made or your novel written. There's no secret sauce, no easy button. It just takes effort and the ability to keep yourself motivated...and feed the cast and crew. Always feed them. Even if the budget is zero... No excuses.
One more stolen bit paraphrased from Kevin Smith: Be encouraging because you never know who might be the one to write your next favorite book, direct your next favorite film, or write that song that gets you through the tough times. Encouragement is free, folks.
Dave Grohl said this about music, but it applies:
