In his second year at Cambridge he wrote to a small number of agents, and one of them, his later agent Josh (Joshua Woodford), introduced himself after a show at Edinburgh a year later.[8](https://www.5elevenmag.com/post/milo-callaghan) He is listed by his agency with skills including guitar and singer-songwriting, capoeira, free running and parkour, Thai boxing, and windsurfing, and a height of 6 feet 1 inch.[2](https://www.hamiltonhodell.co.uk/talent/milo-callaghan/)
## Television career
Callaghan's first screen credit was the Starz historical drama *The Spanish Princess*, in which he played Henry Stafford in five episodes broadcast in 2020.[4](https://www.usanetwork.com/usa-insider/the-rainmaker-milo-callaghan-tv-movie-career) He followed this with guest appearances as Thomas Watts in *FBI: International* (2022), Kai Shelley in the BBC medical series *Casualty* (2023), and Alan K. Sullivan in the *Doctor Who* episode "Dot and Bubble" (2024).[3](https://www.tvmaze.com/people/291466/milo-callaghan)
In 2024 he appeared in two higher-profile series. In *Rivals*, the Disney+ adaptation of [Jilly Cooper](https://www.edgepedia.org/jilly-cooper)'s 1988 novel starring [David Tennant](https://www.edgepedia.org/david-tennant) and [Aidan Turner](https://www.edgepedia.org/aidan-turner), he played Seb Burrows, a journalist at an independent commercial television station that becomes a pawn in the central rivalry.[4](https://www.usanetwork.com/usa-insider/the-rainmaker-milo-callaghan-tv-movie-career) • [2](https://www.hamiltonhodell.co.uk/talent/milo-callaghan/) In *Dune: Prophecy*, the HBO prequel series to the *Dune* films, he played Orry Atreides.[4](https://www.usanetwork.com/usa-insider/the-rainmaker-milo-callaghan-tv-movie-career) He also played Joe in the Irish teen comedy series *Video Nasty*, produced by Deadpan Pictures for BBC iPlayer.[2](https://www.hamiltonhodell.co.uk/talent/milo-callaghan/) • [4](https://www.usanetwork.com/usa-insider/the-rainmaker-milo-callaghan-tv-movie-career)
## The Rainmaker
*The Rainmaker*, an adaptation of [John Grisham](https://www.edgepedia.org/john-grisham)'s 1995 novel developed by Michael Seitzman and Jason Richman, casts Callaghan as Rudy Baylor, a role played by [Matt Damon](https://www.edgepedia.org/matt-damon) in [Francis Ford Coppola](https://www.edgepedia.org/francis-ford-coppola)'s 1997 film adaptation. The series premiered on USA Network on August 15, 2025, and was Callaghan's first leading role on screen; it was also part of USA Network's return to original scripted programming after several years of reality shows and sports.[6](https://apnews.com/article/7e4ece60e84e0d230f2e83a802223d21) The cast includes John Slattery as attorney Leo F. Drummond, Lana Parrilla as Jocelyn "Bruiser" Stone, Madison Iseman, and P.J. Byrne.[6](https://apnews.com/article/7e4ece60e84e0d230f2e83a802223d21)
Preparing the role involved several layers for a British actor playing a Tennessee lawyer. Callaghan worked with a dialogue coach on a Memphis-area Southern accent, studied American courtroom speech by reviewing trials including the O.J. Simpson murder trial and the [Gwyneth Paltrow](https://www.edgepedia.org/gwyneth-paltrow) civil trial, and read the novel during production. He described the difficulty of relearning rewritten deposition scenes overnight while keeping the dialect consistent.[6](https://apnews.com/article/7e4ece60e84e0d230f2e83a802223d21) The first season ran ten episodes and followed Rudy's medical malpractice case against a major healthcare corporation.[9](https://www.tvinsider.com/1288489/) USA Network renewed the series, and season 2 premiered on October 16, 2026.[9](https://www.tvinsider.com/1288489/)
