Exit the moppet ballerino, enter the Follies girl: The incoming Broadway revival of “Funny Girl” has booked the Imperial Theater for its upcoming spring run, filling the space to be vacated by “Billy Elliot.”Lauren Ambrose and Bobby Cannavale star in the Bartlett Sher-helmed revival, a production that had previously announced plans for Broadway but had been waiting for a theater to become available. Revival will have a pre-Rialto tryout in L.A. at Center Theater Group’s Ahmanson Theater Jan. 15-Feb. 26. This latest incarnation of “Funny Girl” will mark the first Broadway staging of the show since it bowed in 1964 in a production that helped launch the career of Barbra Streisand. Further casting for the new incarnation has not yet been locked in. Story centers on Fanny Bryce (Ambrose), the Ziegfeld Follies star, and her relationship with a gambler (Cannavale). Tuner has music by Jule Styne, lyrics by Bob Merrill and book by Isobel Lennart. Revival arrives on the Main Stem with a team of commercial producers including Bob Boyett, Sonia Friedman Prods., Jean Doumanian, Stacey Mindich, Tim Levy and Center Theater Group. Show targets an April opening, with an exact date still to be determined. Earlier this week “Billy Elliot” announced it would shutter after a Broadway run of about three years. That musical is set to close Jan. 8.
