Honestly, if you go back and watch Public Enemies today, it’s not the CGI or the massive shootouts that stick with you. It’s the way Johnny Depp looks at the camera. He’s playing John Dillinger, the 1930s bank robber who became a folk hero, and there’s this weird, quiet intensity there. It wasn’t just an actor playing a "bad guy." Depp felt like he actually knew the guy.
He basically said as much during the press rounds in 2009. He didn't just study the scripts; he looked for a "ghost."
The "Moonshine" Connection: How Depp Found the Voice
You’ve probably seen Depp play some pretty wild, over-the-top characters. Jack Sparrow, Mad Hatter—the works. But for John Dillinger, he went the opposite direction. He went home.
Depp was born in Owensboro, Kentucky. That’s only about 70 miles from where Dillinger grew up in Indiana. When he was trying to figure out how a Great Depression-era outlaw would sound, he didn’t go to a dialect coach first. He thought about his own family.
He famously mentioned that he based the voice on his grandfather, who drove a bus by day and ran moonshine by night, and his stepfather, who actually spent time in Statesville Penitentiary. It’s that specific, Southern-Midwestern drawl—a mix of charm and "don't mess with me" that made the character feel lived-in.
Finding the man in the details:
- The Voice: Since there are no surviving audio recordings of the real John Dillinger, Depp listened to recordings of Dillinger's father to "do the math" on the accent.
- The Clothes: Director Michael Mann is a notorious perfectionist. He gave Depp original shirts and toiletries that Dillinger had actually left behind while running from the feds.
- The Bed: During the filming of the Little Bohemia shootout, Depp actually slept in the same room—and the same bed—where Dillinger had stayed. Imagine waking up to staged gunfire in the exact spot where the real guy almost died. That’s a level of "method" that most people would find exhausting.
Why John Dillinger Was Different
The movie captures something people often forget about the 1930s. The public didn't hate bank robbers. They hated the banks.
People were losing their farms and their life savings. Then comes this guy in a sharp suit who leaps over bank counters like a rock star and tells the patrons, "We're here for the bank's money, not yours." Depp plays that charisma perfectly. He’s not a monster; he’s a professional who knows he’s on borrowed time.
There's a scene where Dillinger walks right into the Chicago Police Department's "Dillinger Squad" headquarters. He just wanders around, looking at the photos of his own gang on the walls. He even asks the score of a baseball game. It feels like a Hollywood invention, right?
It actually happened.
The real Dillinger had this terrifyingly high level of confidence. He knew the FBI (or the "Bureau of Investigation" as it was then) was disorganized. He knew Melvin Purvis—played by a very stiff Christian Bale in the film—was struggling to catch up with a new kind of motorized crime.
Fact vs. Fiction: What the Movie Got Wrong
Look, Michael Mann wanted "authenticity," but he also wanted a good movie. If you’re looking for a 100% accurate history lesson, Public Enemies takes some massive liberties.
First off, Dillinger and Melvin Purvis never had a face-to-face chat. In the movie, they have a tense meeting in a jail cell. In reality? They never met while Dillinger was breathing.
Then there's the death of "Baby Face" Nelson and "Pretty Boy" Floyd. The movie makes it look like they were picked off before Dillinger. In the real timeline, they actually outlived him. Nelson didn't go down until months after Dillinger was shot outside the Biograph Theater.
Also, the movie portrays Dillinger as a bit of a killing machine. Most historians agree he probably only killed one person—a police officer named William O'Malley during a robbery in East Chicago. He wasn't the trigger-happy assassin the feds made him out to be; he was a heist artist who used speed and Tommy guns to intimidate, not necessarily to massacre.
The Legacy of the Performance
What really makes the Johnny Depp John Dillinger connection work is the theme of the "dying breed."

The movie is about the end of an era. The old-school, charismatic outlaws were being replaced by the organized "Syndicate" (the Mob) and the high-tech, scientific federal government under J. Edgar Hoover.
Dillinger was too loud for the Mob and too fast for the old cops. He was stuck in the middle. Depp plays him with this underlying sadness, like a man who knows the world is changing and he’s not invited to the future.
Lessons from the Dillinger Story:
- Trust is a liability. Dillinger wasn't caught because he was "outsmarted" by a detective. He was sold out by the "Woman in Red," Anna Sage, who was facing deportation.
- Adapt or die. The FBI won because they started using wiretaps, fingerprints, and interstate coordination. Dillinger stayed "old school," and it eventually trapped him.
- Narrative is everything. Dillinger was a master of PR. He played to the cameras and the crowds. Even today, we remember him as a "social bandit" rather than a common thief because he knew how to tell his own story.
If you haven't seen the film in a while, it's worth a re-watch just to see the contrast between Depp's quiet performance and the absolute chaos of the digital cinematography. It’s gritty, it’s loud, and it’s probably the most honest look we’ll ever get at the man who was once Public Enemy Number One.
Next time you're looking for a deep dive into the 1930s, check out the book the movie was based on: Public Enemies: America's Greatest Crime Wave and the Birth of the FBI by Bryan Burrough. It fills in all the gaps the movie left out, especially regarding the internal politics of Hoover’s early FBI. It’s a wilder story than anything Hollywood could script.
