• Harris said that writing the final scene was "a really exciting fight" for him.

Warning: Spoilers ahead for "Zola."

"Zola" screenwriter Jeremy O. Harris said that the movie's abrupt ending reflects how the friendship between the two main characters is over for good.

The film, out now, is adapted from stripper A'Ziah "Zola" King's viral 2015 148-tweet thread about Zola (played by Taylour Paige) and Jessica (called Stefani in the movie and played by Riley Keough) heading to Florida to make money pole-dancing at strip clubs.

While the Twitter thread by King comes to an end with Zola flying home to Michigan, the movie ends abruptly with the two women driving Stefani's boyfriend Derrek (played by Nicholas Braun) to the hospital.

When asked about the movie's ending, Harris told Insider in June that writing the final scene was "a really exciting fight" for him and director Janicza Bravo. He said that they considered a few different options for how to end the film, from doing "something really historic" for the closing sequence to having a "cinematic montage" of Black-white female friendships.

Ultimately, Harris said, he and Bravo settled on ending the movie when "that trust" between Zola and Stefani, who share a contentious relationship throughout the film, "is fully broken."

Harris recalled Bravo telling him "the story that we're telling is how these two girls stopped being friends" and that she believed "the movie needs to end when they stop being friends."

It's a fitting ending, too, considering that King's now-deleted Twitter thread began with the infamous line "Y'all wanna hear a story about why me & this b---- here fell out???????? It's kind of long but full of suspense."

Even before reading the rest of the thread, social-media users knew that Zola and Jessica (Stefani in the movie) don't exactly enjoy a long-lasting friendship.

Harris said he got 'deep inside the soul of this young, young woman' while writing the screenplay for 'Zola'

While the ending to "Zola" might have been different from the Twitter story the movie is based on, Harris said he and Bravo knew they wanted to "maintain almost every tweet" in the film adaptation.

In the thread and the movie, Zola and Stefani are accompanied by a mysterious man. Called Z in the thread, but renamed X in the film, he's played by Colman Domingo.

At first, Stefani introduces him to Zola as her roommate but it's later revealed that he is actually Stefani's pimp. What is even more puzzling is that social-media users and movie-goers don't know his name for more than two-thirds of the story.

"I think it's like tweet a hundred when you finally realized that the entire Twitter thread, you don't know his name," Harris told Insider of the character. "And we were like, 'Oh, well we have to keep that tweet in. We have to figure out how to make that work [in the movie].' So that was a joke."

The movie handles the joke by addressing it as soon as X shows up on-screen when Zola says she wouldn't find out what his name was for two whole days.

Harris said that for him and Bravo "the baby was the joke about the name" because the way King kept X nameless for most of her thread was "such an insane thing to pull off."

"Zola" is in theaters now.
