So you’ve recently completed this amazing big budget blockbuster screenplay . Now you want to make something happen with it. The problem is: No one is biting.
Why?
Because big budget spec scripts don’t sell. (You can read more about that in my previous article.)
Maybe your best next step is to consider adapting your screenplay into a novel. Although this is the reverse of how the process usually works (books adapted into movies are more common), that doesn’t mean this road is any less viable. In fact, adapting your completed screenplay into a book should be a go-to course of action if your screenplay is still gathering dust after a year or two.
Recently, I decided to take a big budget fantasy script that was a pet project of mine and transform it into something marketable. That meant tossing aside the idea that this script would be sold on spec (it wouldn’t) and taking a more realistic approach: Turning my screenplay into a novel.
Having embarked on this new experience, I can now offer some helpful advice on what to expect when you adapt your spec script into a book.

Why Adapting Your Screenplay Into a Novel is a GREAT IDEA
1. It’s far easier to get a book published than to get a screenplay made. And lastly, a successful novel will help build the IP required to support that big budget sci-fi/fantasy/superhero spec script you wrote.
2. You already know the characters, story and world. Much of the hard work is already done. Writing the novel will also help deepen your understanding of each of these elements, in turn making the script even better (assuming you update it).
3. Simply put: It’s fun! So much more fun than I can put into words. The rush of writing those big visuals as they splash and evolve across the screen is simply indescribable. Why not enjoy what you love doing most?
CHALLENGES TO EXPECT
1. You Can’t Just Paste a Screenplay and Expect a Novel to Happen.
I cannot understate this point. Movies and book simply aren’t the same. This may seem obvious at first, but the differences are deeper and truer than even most professional realize. They handle storytelling in different ways. For you, this means you can’t just copy and paste your script into prose format. You will have to invest time in writing the book for the medium.
J.R.R. Tolkien once stated that his genre-defining epic The Lord of the Rings could not be filmed for this very reason. The effort to successfully adapt the series to screen required monumental effort by Peter Jackson and his many, many teams of moviemakers.
Cut-and-paste didn’t work going from book-to-screen, so it won’t work in reverse, either.
2. Not Everything Translates from Screen to Page.
Certain storytelling constructs will require additional effort to make them work. For example:
- Novels reveal the internal monologue / film does not
- Action thrives on screen / requires more work in prose
- Screenplays are leaner, less forgiving / books have more freedom to explore
- Novels are longer, so can have wider variance in structure / script structure is fairly rigid
3. You Will Have Gaps — Big Ones.
Whereas a screenplay has the magical effect of stimulating the imagination with minimal words on the page, and a movie has the luxury of using dedicated specialists to realize design for costumes, sets and atmosphere, a novel must do most of this for itself. For example, characters will require more description to capture the reader’s imagination.
Likewise, objects, sensations, visuals, impressions and feelings will take a little more exploration to make the same impact. Things you wouldn’t normally have to mention in a screenplay (because their presence is implied by the location, for example) often demand a mention to help set the scene as well.
Writers like J.K. Rowling and J.R.R. Tolkien demonstrate a remarkable gift for writing minimal description to communicate their ideas. Storytellers like Herman Melville prefer to wax poetic for pages (even chapters) at a time about the virtues of a painting. Most of us lie somewhere in between.
Either way, be prepared to put some extra time into fleshing out the character gaps, locations, and the thoughts and sensory interpretations of the character, possibly even the narrator (if applicable). It helps to think of your screenplay as an annotated outline for your book.

4. Writing the Book Version Will Make You Want to Rewrite Your Spec Script.
Simply throwing a rough draft of your book onto the page will give you the opportunity to dive deeper into your characters and story world than you would have previously. I found it helpful to push myself through the end of a completed rough draft of the novel before taking a step back to reassess how my new discoveries might impact the next draft of the original spec script.
In case you’re wondering: Yes, I did simultaneously rewrite the script and the book. And yes, it was hair-pullingly difficult. In the end, both story forms benefited greatly from the process and I have no regrets.
(NOTE: Don’t feel obligated to rewrite your script—not at first, anyway. You can still use it as-is for a writing sample. Rewriting your script may not be worth the effort.)
5. Screenwriting is More Fun, but Novel Writing is More Fulfilling.
This isn’t so much a challenge as a forewarning. Nothing beats the rush of writing a screenplay, especially when you are wrapped up in the intensity and immediacy of the moment. Compared such an amazing experience, writing a novel can feel a little bit like a letdown. Not that it’s bad—because it isn’t—but in many ways, it takes longer in a book to cover the same ground as in your screenplay. That can be frustrating.
Still, in the end, writing a novel gives you so much more freedom to express yourself and explore the characters, voices and world than you get in the restrictive screenplay format. Because of this, creating a novel can be more fulfilling in the end. Even screenwriting great William Goldman recommended writing something other than screenplays on the side.
I still love my spec screenplay (it was a vanity project, after all), but I’m even more proud of the book that came out of it. Additionally, the novel version also has a dramatically higher likelihood of being read by other people than my spec script.
And let’s face it, there’s nothing like sharing your story with the world.
