Stage and screen star Andrew Rannells is returning to the Great White Way in Falsettos this fall. As a fan of the 1992 production, Rannells recently stopped by The Late Show to tell Stephen Colbert how excited he is to celebrate unlikely love alongside Broadway faves like Christian Borle and Stephanie J. Block. However, he definitely won't forget his "dirtier" roots in works like The Book of Mormon and HBO's Girls. "During Mormon, we were wondering: 'I don't know if the middle of the country's gonna go for this.' And Trey [Parker] would be like 'Well, I'm from the Midwest. Rannells is from the Midwest. That's where all the dirty people are from.'" Whether he's playing delightfully dirty, squeaky clean, or anywhere in between, we're glad to have Rannells back on Broadway. Watch the hilarious interview below, and catch Falsettos at the Walter Kerr Theatre beginning September 29!
