Tony Award nominee Rory O’Malley is getting ready to step into a new role – in the Broadway production of Hamilton. He will begin playing King George on April 11, taking over for Jonathan Groff, who is going to start working on David Fincher’s new Netflix drama series, Mindhunter.

O’Malley earned a Tony nomination for his performance as Elder McKinley in The Book of Mormon. He also appeared in the Broadway production of The 25th Annual Putnam County Spelling Bee, and off-Broadway in Little Miss Sunshine and Nobody Loves You. O’Malley has appeared on several television series, including Partners, Law & Order: SVU, Nurse Jackie, The Good Wife, Dreamgirls, and 1600 Penn.

O’Malley will be the fourth actor to play King George in Hamilton. Brian d’Arcy James portrayed him off-Broadway before Groff took over. Groff was briefly replaced by Andrew Rannells last fall while Groff filmed Looking.

Hamilton has a book, lyrics, and music written by Lin-Manuel Miranda and is directed by Thomas Kail. It was inspired by Ron Chernow’s 2004 biography of Alexander Hamilton. The musical describes the early days of the United States as the Founding Fathers debated policy and struggled to form a new nation.

The show tells the story of Alexander Hamilton, a man who came to America as an immigrant and became a war hero. He rose to the position of Secretary of the Treasury and inspired faith in the burgeoning American economy.

The story is told through rap, hip-hop, and R&B ballads. Unlike the Founding Fathers, who were of Western European descent, many of the actors in the play are African American and Hispanic. The play uses a revolving stage to convey the sense that events are constantly in motion and situations are rapidly evolving.

The play stars Miranda in the role of Hamilton, Christopher Jackson as George Washington, Phillipa Soo as Eliza Hamilton, Leslie Odom Jr. as Aaron Burr, Okieriete Onaodowan as James Madison, and Daveed Diggs as Marquis de Lafayette/Thomas Jefferson.
