The brewing tuner adaptation of “Diner” has pushed back its Broadway dates, shifting its proposed opening from this spring to the fall.Scott Zeiger, who produces with Brian Becker under the banner of Base Entertainment, attributed the delay to the logistics of the work the creative team wants to accomplish on the musical, which was further developed in a four-week Gotham workshop in November. “It has become very clear the direction in which we need to continue to take this new American musical,” Zeiger said in a statement. “Early fall dates work better for all involved and an announcement of Broadway theater and dates will be forthcoming.” “Diner” would have been one of the higher-profile offerings on the Rialto’s spring sked, given the involvement of composer Sheryl Crow (in her first stage project) and book writer Barry Levinson, the writer-director on whose well-known 1982 pic the musical is based. Delay was looking increasingly likely, given that no specifics of the show’s spring run had been set since its April 10 opening was announced over the summer. The move comes after the production also ditched a scheduled fall tryout run in San Francisco, a cancellation blamed on the need to retool the show for one of Broadway’s smaller venues, which producers deemed more likely to become available than a larger house. Further details regarding the fall preem of “Diner,” to be directed and choreographed by Kathleen Marshall, remain to be confirmed.
