Matthew B. Mills and Mystake: Everything You Need to Know

Who Is Matthew B. Mills?
Most people who come across Matthew B. Mills find him through his acting work. He is from Alma, Michigan — not exactly a Hollywood zip code — and has spent the last several years doing what most actors from small Midwestern towns have to do: grind, take the right roles when they come, and build a resume that speaks for itself.

What makes Mills a bit different is that he is not just an actor. Matthew B Mill’s IMDB profile lists him under both Actor and Stunts, and that dual classification is not just administrative. It reflects a genuine physical ability that most performers his age either do not have or have not bothered to develop. In a business where versatility is currency, that matters.

He is based between Michigan and Los Angeles — a split that, practically speaking, says a lot about where he is in his career. Rooted enough to keep the day-to-day real, but present enough in LA to stay in the running when parts come up. It is a juggling act that a lot of working actors recognise.

His Film Work So Far
Three credits anchor his current profile:

Babylon (2022)
Babylon is the kind of credit that opens doors. Damien Chazelle directing, Margot Robbie and Brad Pitt at the top of the call sheet, Paramount behind it — this was not a small production. Mills appeared as a USC Football Player, which might sound like a minor role on paper, but getting cast in a film of that scale means you passed through a serious audition process and held your own on a major set. For an emerging actor, that experience is hard to overstate.

The film itself was a sprawling, divisive piece of work — loved by some, too much for others — but it did what prestige productions do: it generated conversation, won awards attention, and put everyone involved in front of a wider industry audience. For Mills, being part of Babylon is a legitimate credential, not just a line on a page.

The Raven of Baltimore City (2025)
This is the credit that shows what Mills can actually do. The Raven of Baltimore City is a darkly comic indie crime film — the kind of project that tends to attract actors who want to work rather than just be seen. The story follows a comic-book-obsessed man who decides to become a real-life masked superhero after a violent encounter, only to realise somewhere along the way that he might be more villain than hero. It is a specific, character-driven concept, and director James Frommeyer gave it genuine texture.

Mills is in the principal cast alongside Eli Sandhaus, Jenny Kuhlthau, and Matthew Boykin. That is a proper role in a proper film — not a cameo, not a glorified extra. The genre suits him too. Crime-adjacent, physically demanding in places, with room for a performance that does not have to rely on dialogue alone.

Christmas Eve (2026)
Details on Christmas Eve are still thin, but it is on the IMDB page and it is dated 2026 — which means Mills has been working consistently enough that another project is already in the pipeline. In this industry, that kind of steady output is often more telling than any single big credit.

What Sets Him Apart on Screen
The stunt background is worth dwelling on for a moment, because it does more than make him easier to cast in action sequences. Actors who can perform their own stunts tend to be more comfortable in their bodies on camera generally — there is a physical ease that comes through even in quieter scenes. Directors notice it. Cinematographers notice it. And in an industry that is increasingly drawn to performers who can do more with less, it is an asset that compounds over time.

His build and presence are self-evident from what we have seen on screen. But the point is not just that he looks the part — it is that he has put in the work to back it up. That combination of dramatic range and physical credibility is genuinely hard to find, and it is probably why a Midwest-born newcomer landed a role in one of Paramount’s biggest releases of 2022.

The Other Career: How Matthew B. Mills Built Mystake
Somewhere between early film roles and building a life between two cities, Mills also made a business decision that would end up defining another significant chapter of his story.

In 2019, he invested in a startup called Mystake. This was early — before the platform had found its footing, before it had the user base or the catalogue that it has now. Investing early in anything is a gamble (the irony of the industry being noted), and plenty of early-stage gambling platforms from that era quietly folded. Mystake did not.

From 2019 to 2022, Mills served as a board partner, contributing to the direction of the business during a formative period. Then, in 2022, he stepped into a more central role, taking on the position of managing partner and CEO. What followed was the kind of growth that people in the industry point to when they talk about what a well-run platform can become: Mystake expanded into a full fiat-based casino with over 5,000 games, a competitive sportsbook, and a bonus structure that gave it a genuine edge in a crowded market.

It is a real business achievement. Not a passive investment that happened to pay off, but an active leadership role during a period of meaningful expansion. Mills was in the room when the decisions were being made.

And yet, outside of gambling industry circles, this chapter of his career barely comes up. His acting work dominates the public-facing profile. Whether that is by design or simply because the two worlds do not talk to each other much is hard to say with certainty — but the gap is noticeable once you start looking.

The Bigger Picture
Matthew B. Mills is harder to categorise than most profiles about him suggest. The straightforward version of the story — young actor from the Midwest builds a Hollywood career — is real, but it is only part of what is going on.

The Mystake chapter gives him something that most actors at his career stage simply do not have: financial independence, industry credibility in a high-growth sector, and the kind of operational experience that could translate into producing or financing film projects down the line. Many of the most durable careers in Hollywood belong to people who figured out how to operate on both sides of the business-creative divide. Mills appears to already be living that model, even if the two sides of it are not always visible at the same time.

What the next few years look like probably depends on how Christmas Eve lands, what roles come after it, and whether Mills chooses to bring his business background more openly into his creative work. The ingredients are there for something genuinely interesting. Whether that potential gets realised is the only real open question.

For now, he is a working actor with a growing resume, a stunt background that keeps him in demand, and a business track record that most people in his position would not have thought to build. That combination is unusual. It is probably worth paying attention to.
