An hour into a recent documentary on the opioid litigation, plaintiffs lawyer Paul Farrell Jr. nears his breaking point. Running out of money, he sells a West Virginia home to free up cash and branches out on his own after the financial strain of supporting the opioid case fractured his law firm.

"This case completely absorbed me,” he said in the 2025 PBS documentary The Bitter Pill as he tapes up a handwritten sign advertising his new law firm. “I'm going to bring it to some type of magic or tragic ending.”

Almost six years later, Farrell’s story has turned out to be both. The massive multidistrict litigation brought against drugmakers, distributors and pharmacies over the opioid epidemic has amassed more than $50 billion in settlements for states and municipalities, earning Farrell and scores of other lawyers hefty legal fees.

At the same time, Farrell suffered a bruising loss in the case he cared about most: a federal bench trial on behalf of his West Virginia hometown accusing drug distributors, a largely unseen part of the pharmaceutical supply chain, of causing the opioid epidemic.

The Bitter Pill chronicles Farrell’s single-minded focus on the case for almost nine years and counting. It traces the arc of the Cabell County, West Virginia, case in particular, detailing how the municipality—fed up with the way opioid addiction has decimated its community—opted out of national settlement talks to bring its case to trial.

“I’m going to expose to the entire country exactly what’s happened for the past 20 years,” Farrell says in one scene ahead of trial.

Los Angeles-based documentary filmmaker Clay Tweel condensed 220 days of filming starting in 2017 into the 82-minute film. The final product gives viewers a look at behind-the-scenes litigation drama and rarely seen depositions; follows paramedics as they respond to overdoses; and tracks Farrell as he goes from a self-proclaimed “hillbilly lawyer” in West Virginia to a nationally acclaimed trial attorney. 

In the film, Farrell seems confident he can shake a payday from the drug distributors. However, cameras catch the moment on July 4, 2022, that his team learned—as Farrell was celebrating his 50th birthday—that a federal judge had completely ruled against them in the Cabell County case.

U.S. District Judge David Faber concluded “there is nothing unreasonable about distributing controlled substances to fulfill legally written prescriptions,” rejecting Farrell’s public nuisance theory against the distributors.

The film shows Farrell slumped in an armchair after seeing the verdict, "5" and "0" balloons still hanging in his parents’ living room and a blow-up birthday cake deflating in the front yard.

“We lost,” Farrell says to the camera, dejected. “We left the decision in the hands of an 80-year-old federal judge who just simply, in his own mind, didn’t buy that it was anybody’s fault other than the addicts'.”

Speaking recently from Puerto Rico, where he now lives, Farrell says he agreed to let Tweel and his crew trail him so he could convey the same sense of transparency that he was trying to force out of the defendants.

He says the filmmaking process wasn’t always enjoyable, because he hated getting mic'd up and didn’t always want to spend extra time after long days of court or depositions dissecting what had happened. In the end, he’s glad he went through with it. The final film, Farrell says, “does a really good job of capturing the gestalt of the feeling of what I was doing.” That includes “how there were some very lonely times,” he says. “But it also fairly depicts my resolve, my determination.”

Tweel says he tried to distill the complex litigation for a lay audience and even managed to dramatize discovery, a usually dry aspect of litigation, by focusing on the high stakes of gaining access to a federal database tracking the distribution of every opioid pill. The plaintiffs’ team finally succeeded, and the documentary shows how the resulting data became publicly available and helped build the base of their case.  

Defense lawyers don’t make it into the documentary. For one, they declined to take part. For another, cameras weren’t allowed in any of the federal court hearings. The drug distributors have long denied helping fuel the opioid crisis, arguing they had robust systems in place to flag suspicious orders. In 2021, the three major distributors agreed to pay up to $21 billion over 18 years to end their role in the broader litigation while continuing to dispute the allegations.

Farrell says very little was off-limits to the cameras, but he did draw a line at anything that could put attorney-client privilege at risk. As the litigation grew larger, he also balked at times if the cameras tried to trail him to court, not wanting to give the wrong impression to his co-counsel or the defense.

Tweel says one infamous litigation-related documentary weighed on his mind while making the film: Crude, which chronicled attorney Steven Donziger’s battle against Chevron Corp. over oil pollution in Ecuador. Gibson, Dunn & Crutcher famously gained access to filmmaker Joe Berlinger’s footage during discovery, using outtakes to build a fraud case against Donziger.

Tweel says he tried to balance being there for important moments with giving Farrell space to do his work. “That’s the dance you constantly have to do,” he says.

While The Bitter Pill ends on the West Virginia trial loss, the case gained new life in October, weeks after the film first aired on PBS.

The Richmond, Virginia-based 4th U.S. Circuit Court of Appeals overturned Faber’s ruling and sent it back to the lower court, ruling that an overdistribution of opioid pills could constitute a public nuisance and that the judge erred in parts of his analysis.

Even as he continues to push the Cabell County case, Farrell says the broader litigation has done much of what he set out to accomplish: “We brought visibility. We brought accountability.”
