Tuner moving to B'way

No “Doubt” about it: Playwrights Horizons’ hit tuner “Grey Gardens” is stepping into Broadway’s Walter Kerr Theater in October, after “Doubt” shutters July 2.

East of Doheny, the company whose Rialto credits include “Not About Nightingales,” “Sweet Smell of Success,” and the Deaf West revival of “Big River,” will produce the show in association with Playwrights, where “Gardens” shuttered April 30 after three extensions.

Based on the 1975 Maysles Brothers doc, tuner follows an eccentric mother-daughter pair who end up living in a squalid mansion in East Hampton. Christine Ebersole, whose performance in the show garnered universal raves, and Mary Louise Wilson will reprise their roles for the Broadway transfer.

Composer Scott Frankel and lyricist Michael Korie provide the score, with a book by Doug Wright (“I Am My Own Wife”) that breaks the story of Edith Beale and her daughter, Little Edie, into two acts separated by more than 30 years. Michael Greif (“Rent”) directs.

Ebersole plays Edith in the first act, then Little Edie in the second, with Wilson taking over as Edith.

Confirmation of the Broadway run reps something of a turnaround on the part of those involved, many of whom originally believed the Great White Way was not in the cards. Since then, though, enthusiasm has grown, with Ebersole prematurely announcing the Broadway engagement at the Drama League awards ceremony May 5, where the thesp picked up an acting trophy.

Of the season’s kudos so far, “Gardens” has garnered two Outer Critics Circle awards (for Off Broadway tuner and for Ebersole’s perf as lead actress in a musical), a Richard Rodgers production award, and an Obie for Ebersole. Show also snagged 12 Drama Desk noms; those laurels are handed out Sunday.

Original cast recording will be released in late summer.

Exact dates and complete casting for the Rialto run have yet to be announced.
