Editor's note: The film was previously titled "Dry Run." This article has been updated to reflect the change to "Dark Waters."

"Dark Waters" is already full of spoilers.

The film shot in Cincinnati is based on a real legal case that, well, The Enquirer has written about many times. We are positive about who is going to win, who is going to lose – and what this revolutionary case meant for big business and environmental safety in this country.

But we think we might know something else about this Mark Ruffalo-helmed drama.

We believe this might be the most major, major motion picture that's called Cincinnati home in years.

Here are our reasons. In three acts:

This is a Cincinnati story, set in Cincinnati.

We've certainly had films set in the Queen City before.

The bad guys in the Bruce Willis-helmed "Marauders" robbed our Downtown banks. The early '90s cult classic, "Airborne," features totally rad teens rollerblading all over town. Cincinnati, of course, is the starting point for that Tom Cruise and Dustin Hoffman Oscar-grabbing road trip in "Rain Man."

But none of those flicks featured a real-life Cincinnati story in real-life Cincinnati.

In "Dark Waters," Mark Ruffalo will play Rob Bilott, a lawyer who still works at Taft Stettinius & Hollister.

It was in those offices, some 20 years ago, that Bilott picked up the phone and spoke the first words to a West Virginia farmer that launched a groundbreaking legal case.

This legal work eventually exposed DuPont's use of a little-known chemical called perfluorooctanoic acid, or PFOA, and helped determine a “probable link” between PFOA and deadly diseases in humans.

Bilott's legal work has won awards. We think the movie version will, too.

We only have a few details, so far, about production. But those details already shine with Oscar gold.

Take Ruffalo. He's been nominated for a couple Oscars for his work in "Foxcatcher" and "Spotlight." He's won a Screen Actors Guild award for his turn in "The Normal Heart."

Anne Hathaway, who is set to co-star as Bilott's wife, Sarah, won an Academy Award for "Les Misérables." And Tim Robbins, who were are guessing will play that West Virginia farmer Wilbur Tennant, won an Oscar for "Mystic River."

And that's just the hardware the folks we will see on screen in "Dark Waters" have on their shelves.

Production company Participant Media has earned 12 Academy Award wins and 56 nominations for films like "Lincoln," "The Help" and "Spotlight."

Critics also tend to love films like "Dark Waters," ripped-from-the-headlines David versus Goliath legal crusades.

Think "Erin Brockovich" or "Philadelphia" or "The Accused."

Director Todd Haynes will return to Cincinnati for "Dark Waters." In 2014, he helmed "Carol," the romantic drama that earned six Academy Award nominations.

That was actually the last time a movie from here earned major award attention, even though it didn't take home any golden men that night. (Last year's "Old Man and the Gun," shot in Cincinnati and Northern Kentucky could get an Academy Award nomination for Robert Redford, but those haven't been announced yet.)

The only film that significantly shot here that has won an Oscar? That's the 30-year-old "Rain Man." (2001's "Traffic" also earned four Academy Awards, but it was only filmed here minimally.)

So, maybe "Dark Waters" will end our Oscar drought?

Because of those heavy-hitters, we think a lot of people will see this Queen City tale.

The movie business is, in fact, already booming here. Just look at 2016: There were more than 10 completed here that year alone.

However, most of those films shot in recent years had a more limited release or have not hit the theaters yet.

Like those Bruce Willis shoot-em-up, bang-em-up heist flicks filmed locally, "Marauders" and "Reprisal," that were mostly straight-to-streaming features.

Or "The Public,"shot at the main public library and starring Emilio Estevez, has appeared at a few film festivals, but now, two years after it was filmed, the thriller still hasn't hit the big screen.

We bet that "Dark Waters" will also buck that trend, too. It's an A-list story, an A-list cast, an A-list director and production company.

That usually adds up to an A-list wide release in thousands of theaters around the world.

Still, if there is anything that Cincinnati films have shown us, it's this: We don't know how the story is going to end until those credits roll. But we will have a lot of fun watching it unfold.
