‘Based on a True Story’: The Vogue of Killer Content

In a September 2022 episode of “You’re Wrong About,” a history podcast, the writer Michael Hobbes noted that the number of serial killers might be diminishing, which could be a problem, he said — for true-crime fanatics, anyway.

“Step it up out there, serial killers,” he said. “You got to produce good content.”

Hobbes was joking, but serial killers and the podcasts devoted to them feed an ever growing true-crime industry worth millions of dollars. Now the eight-episode Peacock satire “Based on a True Story,” which arrived in full last week, poses a troubling question: What if serial killers weren’t only the subjects but also the hosts, or even the producers, of a true-crime podcast?

The idea isn’t entirely far-fetched. The true-crime world is saturated with podcasts that have been criticized as being ethically compromised and flawed, accused of offenses including plagiarism, racial insensitivity and pro-police bias. True-crime TV series have likewise been criticized: the docu-series “The Jinx,” for edits of a killer’s confession; “Making a Murderer,” for its presentation and omission of details; and the scripted drama “Monster: The Jeffrey Dahmer Story,” for humanizing its subject at the expense of Dahmer’s victims.

“Based on a True Story,” created by Craig Rosenberg (“The Boys”), is a dark, comic sendup of true crime and its conventions, clichés and moral compromises. Matt (played by Tom Bateman) is a friendly plumber by day and the feared West Side Ripper by night. When a married couple in desperate need of excitement and cash (the pregnant Ava, played by an also-pregnant Kaley Cuoco, and Nathan, played by Chris Messina) discover his identity, they blackmail him into embarking on a scheme to create a podcast from the killer’s point-of-view.

“Finally, some good luck!” Ava says. “A serial killer has fallen into our laps.”

One central challenge, however, was how — and whether — the creators and cast of “Based on a True Story” could avoid committing the same crimes as the genre it claims to critique. It is, after all, still a comedy about some particularly gruesome murders.

For Cuoco and Messina, it was important to keep the actions of their own characters in proper perspective.

“In my opinion, Ava and Nathan are just as bad as the killer,” Cuoco, who is also an executive producer, said in a recent phone interview. “I know Ava is trying to believe, Well, this is us stopping him. It’s wrong and it’s funny at the same time.”

Messina said, in a separate interview, that figuring out the tone had been a persistent struggle.

“Every day, I would turn to Kaley and say, ‘Is this supposed to be funny or serious here?’” he said. “Obviously, with people being murdered, it’s no laughing matter. But there is a screwball comedy and terror along with a big heart.

“Like, in the Coen Brothers’ ‘Fargo,’ when they are putting someone in a woodchipper. Why am I laughing one minute and horrified the next?”

As the story gets underway, the absurdities quickly mount. In the beginning, Matt is supposed to be merely the interview subject, his voice disguised. But as the plot progresses, he emerges as a de facto showrunner.

He upgrades the locations and equipment. He provides a new edit, changing the beginning, the ending and the music. He rejects every note about the narrative and the brand.

“These seem like completely ridiculous conversations given that you are talking about people who have been murdered,” Bateman said. “And the funny thing is, he’s getting more and more artistically involved because it’s the first time in his life he’s ever felt seen.”

Michael Costigan, an executive producer, said he thought the podcasters’ artistic squabbles also spoke to a common error in the true-crime world: losing track of the reality of the crimes.

“Kaley’s character is pitching her ideas and forgetting something: ‘I’m sitting across from the perpetrator,’” he said. “We thought, This is absolutely talking about a metaphor for how millions of people get lost in stories as escapism. But what are they escaping into? What are they forgetting about?”

Jason Bateman, another executive producer (no relation to Tom), said he had thought a lot about the show’s tone, and wanted to make sure it wasn’t too “silly” or “camp,” grounding character actions in reality. It was, he acknowledged, a difficult line to walk.

Partly as a mirror of their own internal debates, the writers and producers created a character, played by Ever Carradine, who is the mother of a West Side Ripper victim. Her participation in a true-crime panel raises questions of whether she is honoring or exploiting her daughter.

“We wondered in those scenes, what is the line?” Costigan said. “This is her wanting to talk about her daughter but then also participating in this world, too. We’re really hoping that the audience can have their cake and eat it, too — that you see the duality, see the world from both lenses.”

Critics have pointed to recent studies in suggesting that fans of the genre, a large percentage of whom are women, can suffer from a kind of true-crime brain, a sense of heightened fear that is out-of-sync with the overall decline in violent crime of recent decades. It has also, as the advent of the web sleuth attests, created a lot of self-appointed experts. Ava’s wine-and-crime club of true-crime obsessives are fans of a podcast called “Sisters in Crime,” which leads her to believe she has mastered the genre.

“Ava says things like ‘DB’ for dead body,” said Cuoco, who admitted that she is a huge “Dateline” fan. “She talks like she’s actually on one of those shows.”

The same delusion that allows Cuoco’s Ava to figure out that Matt is the West Side Ripper also, unfortunately, leads her to believe she can control a serial killer — and to lose sight of the victims. In the original script, Ava and Nathan were to be the parents of teenagers, but when Cuoco became pregnant, she suggested that Ava be pregnant as well. It helped raise the stakes and address why Ava would be so blinded by her need to make money.

“Her life is chaotic,” Cuoco said. “This is a distraction.”

To find a potential fan base, the characters take an exploratory trip to CrimeCon, a series of real-life conventions for true crime aficionados, held in cities like Las Vegas, New Orleans and Orlando. As the actors and other producers explained, Rosenberg, himself a true-crime fan, had started thinking more about how criminals become celebrities after attending one such event. (A Peacock spokesman said Rosenberg was unavailable to comment because of the continuing writers’ strike.)

“Craig said he heard people there discussing who their favorite serial killers were, as if they were football players,” Tom Bateman said. His character, walking around the convention floor, observes merchandise being sold in his name, as it is for other serial killers. But he isn’t ranking as highly as he thinks he should be.

Cuoco said she had enjoyed making a humorous examination of the genre. But there were some sobering issues about true-crime, she acknowledged, that even this satire couldn’t fully address — including the future of the genre, which she said was “already at an extreme.”

“There is a fine line,” she added. “I do not condone a serial killer doing a podcast in real life. But I feel like I would be one of those people who say, ‘This should be illegal,’ and then probably go in my car and listen to it. We can’t help ourselves.”
