When people talk about Black Mass, they usually start and end with Johnny Depp’s contact lenses. He looked like a ghoulish, blue-eyed lizard, right? It was transformative. But if you look past the prosthetics and the Southie accents, there’s a quiet, crushing performance that actually gives the movie its pulse. I’m talking about Dakota Johnson in Black Mass.
She plays Lindsey Cyr. Most viewers remember her as the girlfriend who stood up to Whitey Bulger. But the real story is a lot messier than what Hollywood squeezed into two hours.
Honestly, the way the film handles her character is kind of a double-edged sword. On one hand, she’s the only person who treats the most feared man in Boston like a regular human being. On the other, the movie cuts her out just as things get interesting.
The Reality vs. The Script
In the film, we see a version of Lindsey that is essentially a moral compass. She’s the mother of Bulger’s only son, Douglas. When tragedy strikes, she’s the one who forces the "monster" to face a reality he can’t shoot his way out of.

But let’s get the facts straight. The real Lindsey Cyr wasn’t just a fleeting character in Bulger's life. They were together for 12 years. Twelve. That’s a massive chunk of time to be the common-law wife of a guy who was secretly running the city through a mix of murder and FBI protection.
She met him in 1966 at a cafe. She was 21; he was 37. In interviews, the real Lindsey has described him as "gorgeous" and a "gentleman." That’s a tough pill to swallow for anyone who has seen the crime scene photos of Bulger’s victims, but it’s the nuance that makes the performance of Dakota Johnson in Black Mass so vital. She had to play someone who saw the "gentleman" while the rest of the world saw the devil.
What really happened to Douglas?
The movie hits the emotional beats of their son’s death hard. Douglas Glenn Cyr died in 1973 at the age of six. It wasn't some slow-burn illness; it was Reye’s Syndrome, a devastating reaction to aspirin given for a viral infection.
In the film, there’s a scene where Dakota and Johnny argue over pulling the plug. It’s heavy. In real life, Lindsey recalled that Bulger was absolutely destroyed by it. He reportedly told her, "I'm never going to hurt like this again." And he didn't. He became colder. More detached.

The movie makes it look like they drifted apart almost immediately after the funeral. In reality, they stayed in contact for years. She even claimed he called her while he was on the run.
Dakota’s Approach to the Role
Interestingly, Dakota Johnson chose not to meet the real Lindsey Cyr before filming. Some actors want that face-to-face time, but she went the other way. She wanted to focus on the script’s version of the relationship—that specific "side of Jimmy" that only a partner sees.
She studied old footage of Lindsey instead. You can see it in her performance: the way she holds her ground. Most of the men in that movie are terrified of Bulger. They should be. But when Dakota is on screen, that fear is replaced by a weary, deep-seated love that’s arguably more dangerous.
Why her screen time was cut short
A lot of critics at the time felt like the women in Black Mass were sidelined. Julianne Nicholson, who plays Marianne Connolly, also gets a powerhouse scene with Depp and then basically vanishes.
It’s a valid critique. The movie is a "boys' club" of gangsters and G-men. But maybe that’s the point? In the world of the Winter Hill Gang, women were often kept in the dark or shoved to the periphery for their own "protection."
Why Dakota Johnson in Black Mass Still Matters
If you watch the movie today, you'll see it was a turning point for her. This was 2015. Fifty Shades of Grey had just come out months earlier. People were ready to pigeonhole her.
Then she shows up in Black Mass with a thick Boston accent, looking like she stepped straight out of a 1970s Polaroid, and goes toe-to-toe with an unhinged Johnny Depp. It proved she could handle heavy, dramatic weight without the "it girl" trappings.
Real-World Facts the Movie Missed
- The Other Women: Bulger wasn't exactly a one-woman man. While he was with Lindsey, he was also involved with Theresa Stanley and Catherine Greig. The movie simplifies this significantly to keep the focus on the emotional core of the son.
- The Timeline: Douglas died much earlier in the real-life timeline than the movie suggests. By shifting the dates, the filmmakers made his death feel like the catalyst for Bulger’s darkest period in the late 70s and 80s.
- The Money: Bulger once won the Massachusetts lottery (a $14.3 million jackpot in 1991). He didn't just stumble into it; he bought a share of a winning ticket from one of his store owners. This kind of "luck" helped fund his later life on the lam.
Take Action: How to Watch and Learn More
If you're revisiting the film or diving into the history for the first time, here is how to get the full picture:
- Watch the "Connolly Dinner" Scene: Pay attention to how the atmosphere shifts. It’s a masterclass in tension, and it sets the stage for why Lindsey’s eventual confrontation with Bulger is so brave.
- Read the Source Material: The book Black Mass: The True Story of an Unholy Alliance Between the FBI and the Irish Mob by Dick Lehr and Gerard O’Neill is way more detailed than the film. It gives Lindsey Cyr the space she deserves.
- Check out "Whitey: United States of America v. James J. Bulger": This 2014 documentary features the real Lindsey Cyr speaking about her life with him. Seeing her talk about the "gentleman" she knew vs. the man on trial is chilling.
Don't just take the movie at face value. The performance of Dakota Johnson in Black Mass is a window into a much larger, much sadder story about a woman caught in the orbit of a man who destroyed everything he touched.
