The Rainmaker is a new legal drama that will start airing on USA Network on August 15, 2025. Based on John Grisham‘s best-selling novel of the same name from 1995, the series is about a young, ambitious lawyer who is fired from a well-known firm. Then he joins a struggling law firm that works out of a former restaurant and sues a powerful hospital for wrongful death. The story is about justice, inequality, and the power of corporations in the legal system.
The series stars John Slattery, Milo Callaghan, Madison Iseman, Lana Parrilla, P. J. Byrne, Robyn Cara, Dan Fogler, and Wade Briggs.
Where Was The Rainmaker Filmed?
The Rainmaker’s filming started in late 2024 and lasted until March 2025. Main filming locations were Dublin and County Wicklow, Ireland, where most of the production took place. The story takes place in South Carolina, but these Irish cities were chosen because they could be used as American settings with the right set design and location styling.
Dublin, Ireland
Dublin is where most of the filming for The Rainmaker took place. The Georgian architecture and modern court-like buildings in the capital city made a great stand-in for South Carolina’s cities. In Dublin, different streets and office buildings were turned into law offices, courtrooms, and cityscapes in the American style. Milo Callaghan and P. J. Byrne, two actors in the show, were seen filming important scenes in Dublin in January 2025. This made the city even more clear as the show’s visual anchor.
St. Mary’s Hospital, Phoenix Park, Dublin
In the series, this building is shown as “North City Hospital”, a key location in the wrongful death case at the heart of the story. The real site is St. Mary’s Hospital, located in Phoenix Park, Chapelizod, Dublin. This active healthcare facility features exterior architecture that allowed it to stand in convincingly for a U.S. hospital.
In the city, production crews also built sets that looked like South Carolina courtrooms and law offices. The crew was able to keep the realistic feel while staying in one place by shooting both inside and outside.
County Wicklow, Ireland
Just south of Dublin, Wicklow offered quieter and more rural settings. Some of the show’s more atmospheric or character-driven scenes, especially those depicting the lawyer’s transition from a high-powered firm to a small legal practice, were reportedly filmed here. Wicklow is often used in international productions due to its diverse landscapes and easy access to Dublin-based studios.
Local casting calls in November 2024 called for extras of all backgrounds, with a particular focus on Black adults to reflect the show’s storyline. The call mentioned that the show was aiming to recreate modern-day South Carolina settings—confirming the careful effort to match the original setting through Irish locations.
Charleston, South Carolina – A Secondary Filming Unit
While the bulk of the filming occurred in Ireland, a small unit from the production reportedly worked on location in Charleston, South Carolina, to capture exterior shots and cityscapes. These were likely used to establish authenticity and give viewers a visual connection to the original U.S. setting described in Grisham’s novel. However, most of the cast scenes were done in Dublin and Wicklow.
Charleston City Hall, South Carolina, USA
Charleston City Hall, located at 80 Broad Street, appears in The Rainmaker (2025) as part of its South Carolina setting. Built between 1800 and 1804, the building is known for its marble detailing, arched windows, and classical architecture featuring Doric, Ionic, and Corinthian columns. It is the second-oldest city hall in continuous use in the United States. Its historic charm and authentic Southern character made it an ideal filming location for courtroom and legal scenes in the upcoming drama series.
Morrison Yard, South Carolina, USA
Morrison Yard, a modern high-rise complex in Charleston, South Carolina, is featured in The Rainmaker (2025) as a visual stand-in for the upscale corporate law firm headquarters. With its sleek glass facade and panoramic city views, the building brings contemporary urban energy to the series. Its design offers a believable contrast to the historic courthouse settings.
The Rainmaker showcases how international filming can creatively stand in for U.S. locations while still delivering a realistic portrayal. Ireland’s role in bringing South Carolina to life for the screen shows the increasing global nature of television production.
