Harvey Fierstein and John Tiffany, a pair of legiters with Broadway tuners on the docket this spring, have recently signed with CAA.

Fierstein wrote the book for “Newsies,” Disney Theatrical Prods.’ much-lauded tuner adaptation of its 1992 box office flop. The Broadway transfer opens in March, following its regional preem earlier this season in New Jersey.

He’s also at work on the musical version of “Kinky Boots” with tunesmith Cyndi Lauper. That project is tentatively targeting a tryout this fall ahead of a Broadway bow later in the 2012-13 season.

Fierstein is one of the few theater folk to have won a Tony in four different categories, including play (“Torch Song Trilogy”), book of a musical (“La Cage aux Folles”), actor in a play (“Torch Song”) and actor in a tuner (“Hairspray”).

Tiffany, meanwhile, helms “Once,” the stage version of the 2006 indie pic that will open on the Rialto in March following a well-received Off Broadway bow. Director initially made his mark in Gotham with “Black Watch,” the international touring hit that proved popular enough to warrant two return visits to New York.

Ahead for Tiffany is a staging of “Macbeth” that will star Alan Cumming as both Macbeth and Lady Macbeth, in a production that preems this summer as part of the Lincoln Center Festival.

Fierstein continues to be repped by manager Richie Jackson at Jackson Group Entertainment and by attorney Ronald Fierstein. Tiffany, meanwhile, is repped in U.K. by Casarotto Ramsay and Associates.
