Who’s in the Cast of The Rainmaker?
Let’s take a look at the talented cast that brings these courtroom regulars to life:
- Milo Callaghan plays Rudy Baylor, the idealistic young law school graduate. Rudy is fired on his first day by powerhouse lawyer Leo Drummond and needs to find an alternative quickly.
- Lana Parrilla stars as Jocelyn “Bruiser” Stone, a tough-talking, outside-the-box attorney who takes a chance on Rudy. She operates her law firm out of a dilapidated taco stand, showing that justice exists everywhere.
- P.J. Byrne stars as Deck Shifflet, a shaggy paralegal who becomes a part of Rudy and Bruiser’s cause.
- Mad Men alumnus John Slattery stars as the intimidating Leo F. Drummond, Rudy’s old boss turned courtroom adversary.
- Madison Iseman is added to the cast as Sarah, Rudy’s law school girlfriend, who now operates in Leo’s employ, creating emotional tension in the legal competition.
- Supporting cast includes Dan Fogler, Wade Briggs, and Robyn Cara, completing a cast replete with veteran actors and up-and-coming talent.
What’s the Plot?
The Rainmaker is about Rudy Baylor, an inexperienced attorney who discovers a massive conspiracy at a corrupt hospital. Having taken on a major healthcare provider, Rudy has to fight against Leo Drummond, the firm that fired him. In the process, he finds not only malpractice, but possibly murder.
The trailer promises a series packed with high-speed drama, explosive courtroom battles, and sudden turns. A car even crashes through a wall in one dramatic scene, yep, it’s that kind of show.
What Makes This Adaptation Stand Out?
The first book was John Grisham’s fastest-selling novel, and the book-to-movie adaptation was a success. But this new Rainmaker series holds out more depth and development, particularly for its characters.
It’s the characters that drew me in,” says showrunner Michael Seitzman. “They leaped off the page in John’s book and were a pleasure to develop in our series.” He also refers to Milo Callaghan, “your next crush.”
Look for a mix of courtroom strategy, interpersonal drama, and moral gray areas. Suits meets The Lincoln Lawyer—but with a distinctive tone consistent with USA Network’s brand.
How Many Episodes in Season 1?
Season 1 of The Rainmaker will have 10 one-hour episodes. Each episode guarantees tension-filled courtroom moments blended with gritty off-court sleuthing and character-driven plot.
Case Files and Car Chases
The trailer indicates that The Rainmaker is not all courtroom drama. There’s a high-octane car chase, dramatic flashpoints, and even a car smashing through a glass wall. It’s got a pulse and heart.
