If you’d asked most people who Milo Callaghan was a couple of years ago, you probably would’ve gotten a blank stare. Or maybe a "Wait, wasn't he that guy in the background of that one period drama?" But things move fast in Hollywood—or more accurately, in the UK-to-US pipeline. Suddenly, the guy is everywhere. From dodging ancient family feuds in Dune: Prophecy to stepping into the massive, Matt Damon-sized shoes of Rudy Baylor, the list of Milo Callaghan movies and tv shows is growing at a rate that’s honestly a bit dizzying.
It isn't just luck. You can tell he’s got that Cambridge Footlights energy—sharp, a little witty, but capable of being a total underdog when the script calls for it.
From the Spanish Court to Arrakis
Most actors start with a "blink and you'll miss it" role in a soap opera. Milo did that too (looking at you, Casualty), but his real entry point was The Spanish Princess. Playing Henry Stafford back in 2020 gave him a taste of the "prestige drama" life. He wasn't the lead, but he held his own against heavy hitters like Harriet Walter. It’s funny looking back at those early episodes because he looks so young, yet he already had that intense stare that casting directors clearly love.
Then came the jump to sci-fi.
Landing a role in the Dune universe is basically the modern-day equivalent of being knighted. In Dune: Prophecy, he played Orry Atreides. It was a brief but vital appearance that connected the dots for the legendary Harkonnen/Atreides feud. Honestly, being part of a franchise that huge before you've even hit your late twenties is a massive flex. It proved he could handle the "green screen and heavy lore" side of the industry without looking like a deer in headlights.
The Big Break: The Rainmaker and Beyond
But let’s get real for a second. The reason everyone is googling Milo Callaghan movies and tv shows right now is USA Network’s 2025 reboot of The Rainmaker.

Taking on a character previously played by Matt Damon is a ballsy move. Rudy Baylor is a legendary John Grisham character—the scrappy, fresh-out-of-law-school kid who takes on a corrupt insurance giant. When the news first broke, people were skeptical. "Another reboot?" "Who is this British kid?" But then the show aired.
Milo’s version of Rudy is different. He’s got this nervous, kinetic energy that feels more modern. Working alongside John Slattery (who plays the lion-like Leo Drummond) and Lana Parrilla, Milo actually manages to make the courtroom drama feel tense again. In interviews, he’s mentioned how he watched the original 1997 film, "forgot about it," and then just tried to make Rudy a guy who is genuinely just trying to do the right thing despite being way out of his depth.
What Else is on the Resume?
If you’re trying to catch up on his work, here is the current rundown of the essential Milo Callaghan movies and tv shows:
- The Rainmaker (2025): The big one. He’s the lead, Rudy Baylor. It’s a 10-episode slog through legal conspiracies and it’s arguably his best work.
- Video Nasty (2025): A BBC comedy-horror where he plays Joe. It shows off a much darker, funnier side than his legal drama stuff.
- Rivals (2024): He played Seb Burrows in this Disney+ adaptation of the Jilly Cooper novel. Think 80s excess, power struggles, and lots of drama.
- The Strangers: Chapter 1 & 2 (2024-2025): He plays Wayne. If you like being terrified by people in masks, these are for you.
- Doctor Who (2024): He had a guest spot as Allan K. Sullivan in the "Dot and Bubble" episode. It’s a weird, social-media-themed horror story that was actually one of the highlights of Series 14.
He’s also popped up in FBI: International as Julian Watts. It’s one of those roles that shows he can handle the "procedural" style of American TV just as well as the high-concept British stuff.
Why He’s Not Just Another Face
There is a specific kind of nuance Milo brings to his roles. Maybe it's the theater background. Before the cameras started rolling, he was doing Shakespeare and musicals at Cambridge. He even did a pantomime called The Gingerbread Man.

That range matters.
He can do the "serious lawyer" thing in The Rainmaker, but he can also do the "terrified victim" in The Strangers. A lot of young actors get stuck in one lane. They’re either the "action guy" or the "period drama guy." Milo seems to be actively avoiding that. He’s signed with WME now, which usually means we’re going to see him in some even bigger projects soon.
Kinda crazy to think he was just doing student theater a few years ago.
What People Get Wrong
There’s a misconception that he’s just another "nepotism baby" because he landed big roles so quickly. In reality, he spent years doing the grind—short films, theater, and minor guest spots that nobody remembers. His "overnight success" took about five years of constant auditioning.
Another thing: he’s actually British.

A lot of people watching The Rainmaker have no idea. His American accent is so dialed in that it’s almost jarring to hear him speak in his natural voice during press junkets. He’s part of that new wave of UK actors like Tom Holland or Will Poulter who can disappear into an American role so completely that they basically own it.
Where to Watch Him Next
If you’ve already finished The Rainmaker, keep an eye out for the second chapter of The Strangers. It’s a different vibe entirely—much more visceral and less about dialogue.
Also, keep an eye on BBC iPlayer for Video Nasty. It hasn't had the same massive marketing push in the States as his other projects, but it’s where he gets to be the most "himself" in terms of comedic timing.
Actionable Next Steps
- Start with Rivals: If you want to see his range before he became a household name, Rivals on Disney+ is the perfect "mid-tier" role that shows his potential.
- Binge The Rainmaker: It’s on USA Network and Peacock. Don’t compare it to the movie—just treat it as its own 10-hour legal thriller.
- Follow the Projects, Not Just the Actor: Since Milo is picky about his scripts, looking at the directors he works with (like Renny Harlin or Christopher Smith) is usually a good indicator of whether you’ll like the project.
Milo Callaghan is clearly here to stay. Whether he’s in a courtroom or on a desert planet, he’s proved he can carry a show. If you haven't started following his career yet, now’s the time to jump in before he inevitably joins the Marvel Cinematic Universe or something equally massive.
