Christopher Sieber will replace ailing Arrested Development star Jeffrey Tambor as Georges in the Broadway revival of La Cage aux Folles, according to The New York Times.
Sieber, who received Tony award nominations for Shrek the Musical and Monty Python's Spamalot, had been scheduled to star in another revival, playing Billy Flynn in the long-running production of Chicago. Producers of that show released Sieber from his contract to begin rehearsals for La Cage. Tambor dropped out of the show last Thursday, citing complications from recent hip surgery as the reason. Sieber will star in the groundbreaking drag musical opposite another gay actor, Harvey Fierstein. The two men previously worked together in the Broadway production of Hairspray.The date for Sieber's first performance in La Cage hasn't yet been announced.

Kelsey Grammer is swapping TV for the Broadway stage after signing on to star in a new production of La Cage Aux Folles.
The former Frasier star suffered a career setback in early November when his latest TV series, Hank, was axed after just five episodes due to poor ratings.
Its cancellation followed Grammer's previous small screen project Back To You, which was similarly scrapped in 2008, 17 shows in.
But Grammer is now focusing his attention on a revival of the 1983 musical comedy, in which he will play Georges, the owner of a nightclub.
La Cage Aux Folles will open at the Longacre Theatre on April 18th.
The actor last appeared on stage in Shakespeare classic Macbeth in 2000.
