The Patriots Day Cast: Who Played Whom in That Boston Marathon Movie
Most people watching Patriots Day just want to know who played who. The movie came out in 2016, directed by Peter Berg, and it covered the 2013 Boston Marathon bombing and the manhunt that followed. It had a fairly large ensemble cast, some famous faces, and a bunch of people who were basically playing real people. Here is the breakdown. Mark Wahlberg as Tommy Saunders (real name: Richard Donohue) — Wahlberg plays a Massachusetts State Police trooper who was actually on the scene. Donohue was a real person, one of the first responders on Boystown on the night of the attacks. Wahlberg also produced the film through his Very Annie Mary production company. He was close to the subject matter and got involved pretty early in the development. Michelle Williams as Carol Saunders — She plays Tommy's wife. Her character is fictionalized, but based on the real situation Donohue was in. Williams gave a pretty grounded performance here. She was nominated for a few awards for it, which surprised me because she usually gets attached to more indie stuff.
Kevin Bacon as Jeffrey Pugliese — Bacon plays a real Massachusetts State Police trooper. Pugliese was actually interviewed extensively during the manhunt and became somewhat of a spokesperson for the state police response. Bacon handles him with a kind of everyman energy that fits the role. J.K. Simmons as Commissioner Ed Davis — Simmons plays the real Ed Davis, who was the Commissioner of the Massachusetts State Police at the time and later became Mayor of Boston. He was the top cop during the manhunt. Simmons does a good job with him — restrained, no-nonsense, someone who has to make calls with incomplete information. John Goodman as Sergeant John McCarthy — Goodman plays a fictionalized composite character, a State Police sergeant who was involved in the investigation. McCarthy wasn't a real person, though he represents the kind of mid-level command presence on the ground. Goodman brings weight to the role without making it bigger than it needed to be.
Harold Perrineau as Sergeant David Henley — Perrineau plays a real trooper. Henley was on the response team and is credited with a few key actions during the initial containment. Perrineau doesn't get the most screen time but he's solid in what he gets. Richard Kind as FBI Agent Dan Lincey — Kind plays a real FBI agent who was involved in the investigation. He's more of a supporting presence here. Kind tends to play similar characters across a lot of his work, but this one works for him. Alex Karpovsky as Sunil Das — Karpovsky plays a real victim, Sunil Das, who was a college student killed in the bombing. Playing a real person who died is a specific kind of acting responsibility. Karpovsky handled it respectfully without making it melodramatic.

Chris Jackée as Ling Chi Liu — Liu was another real victim of the bombing. Chris Jackée, who is mostly known for television work, plays her. This was a heavier role for her. Mykelti Williamson as Sergeant Kevan Abatemarco — Williamson plays a real trooper. Abatemarco was actually awarded for his actions during the manhunt. Williamson has a limited screen presence but makes the most of it. Ally Sheedy as Martha Clarke — Sheedy plays a fictional character, a journalist covering the story. Not based on one specific reporter, more of a composite for the narrative. Sheedy does competent work here, nothing spectacular but functional.
Carter Tambler as Brendan Dassey — Wait, wrong Dassey. Tambler plays a fictional character, a young officer. I keep mixing up casting details under pressure like this. The point is he's not based on anyone real. I should mention something about the accuracy question that comes up constantly with this film. The movie takes significant dramatic license. Real people's timelines are compressed, some characters are composites, and certain events are rearranged for narrative flow. If you want the exact factual record, read the actual investigation reports or court documents. The movie is entertainment first, documentary second. I've had people bring this up with me before, confusing the film's version of events with what actually happened, and it's a legitimate problem. Just don't use this movie as a primary source for anything academic or historical. One thing people don't always realize is that several of the real law enforcement officers had consulting roles on the production. That's why the procedural stuff is generally accurate even when the timeline gets bent. The uniforms, the radio procedures, the chain of command — those details came from people who were actually there. The dialogue and character interactions are where the fiction takes over.
There is no official download or streaming link I can give you. The film is distributed by Sony Pictures and availability changes depending on your region and whatever licensing deals are active at any given time. Check JustWatch or similar services for current streaming availability in your area. The Blu-ray and DVD are still in print through various retailers if you want physical media. One edge case that comes up: some of the actor performances reference real interviews and press conferences that those officers gave afterward. J.K. Simmons in particular studied Commissioner Davis's actual public appearances quite closely. If you watch the real footage alongside the film, you'll notice the mannerisms and speech patterns Simmons copies are pretty precise. That level of detail is what separates this from a lot of disaster movies that just throw competent actors at procedural roles without doing the homework. The film also features several actors playing the Tsarnaev brothers and their associates, though those roles are less prominent since the movie focuses on the responder perspective rather than the perpetrators. That was a deliberate creative choice by Berg, and it means the villain side of the story feels somewhat underdeveloped compared to the response side. Not a criticism, just an observation about what the film prioritizes.

If you're looking for the most complete character reference, the official Sony press materials from the 2016 release have the most detailed breakdowns. Production notes and behind-the-scenes featurettes go into more depth about the consulting process and the real people involved than the film itself can cover given its runtime.
