TWITTER WATCH: All Hail HAMILTON's King George The Third, The Fourth: Rory O'Malley

HAMILTON welcomed its 2nd Mormon king to Broadway last night as Rory O'Malley, Tony nominee for THE BOOK OF MORMAN, adorned the royal robes to become the fourth Broadway star to take on the plum role of King George III.

The nine-minute role, which consists of the hilarious comedy song, "You'll Be Back," and two equally funny reprises, was originated at The Public Theater by Brian d'Arcy James, who was required to abdicate when rehearsals began for his starring Broadway turn in SOMETHING ROTTEN! Jonathan Groff took over the Off-Broadway run and continued with the smash hit's Broadway transfer.

Another Tony nominee from THE BOOK OF MORMAN, Andrew Rannells, filled in for Groff while he was filming "Looking," but now O'Malley is set for a long reign, as King George The Third, The Second, ventures off to play the lead role in David Fincher's new drama series for Netflix, "Mindhunter."

One of HAMILTON's talented swings, Gregory Haney, snapped a backstage photo of the revolutionary musical's new monarch.

The cast of Hamilton is comprised of Lin-Manuel Miranda (Alexander Hamilton), Daveed Diggs (Marquis De Lafayette,Thomas Jefferson), Renée Elise Goldsberry (Angelica Schuyler),Christopher Jackson (George Washington), Rory O'Malley (King George), Jasmine Cephas Jones (Peggy Schuyler, Maria Reynolds), Javier Muñoz (Hamilton alternate), Okieriete Onaodowan(Hercules Mulligan, James Madison), Leslie Odom, Jr. (Aaron Burr),Anthony Ramos (John Laurens,Philip Hamilton) and Phillipa Soo (Eliza Hamilton).

From bastard orphan to Washington's right hand man, rebel to war hero, loving husband caught in the country's first sex scandal to Treasury head who made an untrusting world believe in the American economy, Hamilton is an exploration of a political mastermind. George Washington,Thomas Jefferson, Eliza Hamilton, and lifelongHamiltonfriend and foe, Aaron Burr, all attend this revolutionary tale of America's fiery past told through the sounds of the ever-changing nation we've become. Tony Award nominee Thomas Kail directs this new musical about taking your shot, speaking your mind, and turning the world upside down.
