The trend seems inescapable. Studios are obsessed with adaptations. The movie business, which used to be powered by original screenplays, is now concerned mostly with converting pre-existing works into films. If it isn’t a comic book, graphic novel, book, foreign film or video game, well…no one’s interested.

That’s the conventional wisdom, at least.

But is it true?

I don’t have any statistics to back the claim up, but let’s stipulate that everyone’s gut sense is true: studios are more motivated to fund adaptations than they are originals.

It’s nothing new, of course.  Movie studios have always chased best-sellers and Broadway musicals, but as culture grows around itself, the movies inspire books that inspire movies that inspire musicals that become CD’s that become movies.

That’s how John Waters can write an original film called Hairspray that becomes a musical called Hairspray that becomes a film of the musical called Hairspray.

Fair enough.

But why are the studios so attracted to adaptations?

Here are some theories (with attendant debunking).

Adaptations Have Marketing Advantages

Competing for eyeballs has become a bloodsport in our culture, and if your movie is based on material that has already planted its flag in the audience’s brain, you can draft behind that awareness.  Of course, this theory doesn’t explain the entire obsession, since many adaptations are of yet-to-be-released novels or extremely obscure comics.

Adaptations Are Easier To Create

Writing something new is hard, you see, whereas adapting a pre-existing work into a screenplay is like a cakewalk.  Easier for the studios, easier for the writers.

Except that’s pretty much never the case.  Movies often differ wildly from their source material, and the process of taking something that wasn’t written to be a movie and turning it into something that is can be brutal and, occasionally, impossible.

I’m a huge fan of the graphic novel Watchmen. I cannot fathom how the screenwriters managed to adapt all that material in a satisfying way. That’s an extremely high degree of difficulty.

Adaptations Do Better At The Box Office

That seems plausible. Think of all the huge hit films from comic books alone. The only problem is that it’s apparently not true.  According to Variety, when you look at the top 20 films from each of the last ten years, you find that movies from original screenplays (and their sequels) actually earn more than adaptations! Don’t believe it? Well, consider The Matrix, all the Pixar films, the Austin Powers movies, Meet The Parents, Rush Hour…even our lowly little Scary Movie series.

So if it’s not money earned, then…?

Adaptations Are Cheaper To Make

Well, that just doesn’t seem very likely. Sure, big original spec sales like the one for Deja Vu can cost a pretty penny, but so can buying out the underlying rights to a bestseller.

So what’s left?

Maybe the dreaded psychological explanation?

Adaptations Feel Less Risky To Make

I’m sure everyone who read The Matrix thought it was a fantastic screenplay. That’s not the Big Question. The Big Question is…should you make it or not?

I’m happy that I don’t have to make those decisions. Not my problem. But for those who do, I suspect that there’s a comfort in making adaptations that goes beyond even the fact of the so-called “built in audience” (which often isn’t really built in).

No one would argue that there’s a natural human tendency that connects “belief in” with “realness,” and I think people view underlying material as more real than screenplays.

Why?

Books aren’t written to be movies. They’re written to be books.  Same for plays and graphic novels and epic songs and video games. They are their own ends. They are, for better or worse, completed works of art.

Screenplays are not. Screenplays are transitional art. They are a theory, an imagining…but of something else.

I’ll argue that studios and producers are occasionally seduced by the notion of adaptation because it grounds them and their risk in something that is very real and permanent.

Does that make sense? No, not particularly, but I’m not here to pen jeremiads against irrationality. We are all irrational to one extent or another. What matters more, I think, is how to navigate the predictable currents of bias when we encounter them.

Hollywood will always buy original scripts. I don’t think they’ve gone completely out of style. Still, given the predilection for source material, more and more screenwriters are doing something very bold and very smart.

They’re writing their own.

My friend Larry Doyle, for instance, had a story for a very funny screenplay, but no one was jumping at it.

So he wrote the very funny book first.  And, somewhat predictably, once it was real, he was hired to adapt his novel into the screenplay he had intended to write in the first place.

The movie is coming out next spring.

My former writing partner did something similar. He and his partner wrote the manuscript for a graphic novel, sold it to a publishing company, and then turned around and sold the film rights to Ben Stiller’s company, where they are writing the script.

I think you’re going to see this more and more. Don’t get me wrong: it’s not required. And there are still plenty of smart producers and executives who know a great original screenplay when they read one.

But…if your material is offbeat or challenging or not “instantly gettable” as the town so often desires, consider this another path. The psychology of the buyer doesn’t always make sense, but just as it’s capable of working against you…

…there’s no reason to think you can’t turn it around and make it work for you.
