It’s your first feature film and you’ve written a massive, multi layered, firing on all cylinders, epic that requires fight scenes on galleons in full sail with hundreds of extras, cue Pirates of the Caribbean, as many lovable, funny characters as Toy Story, and as big a ready made audience as Harry Potter.
It’s the last of this list that is going to affect whether you get any interest or not from a film producer because the first thing you’ll get asked when you go looking for finance is “Who’s your audience?”
If you’ve already got millions of fans, the money will always be found and the film get made. It’s acquiring those fans that’s the hard part but if you can write a feature film, then you’ve already got the plot and layout for a novel and it is far easier to get a first novel published and begin to build that audience than it is to get a first film made.
Start building your reputation in another medium and your fan base will be there to follow you.
