Commercial producers of the new tuner version of “Once” announced the sked for the show’s anticipated Broadway transfer while the musical was in the midst of its opening night perf Off Broadway Dec. 6, locking in a March opening at the Bernard B. Jacobs Theater.

Based on the 2007 Irish indie of the same name, “Once” attracted favorable industry buzz in the run-up to its New York Theater Workshop bow, which has earned largely positive critical notices in Gotham press outlets.

Helmed by John Tiffany and choreographed by Steven Hoggett, the duo behind Scottish touring hit “Black Watch,” “Once” has a book by Enda Walsh (“The New Electric Ballroom,” “Misterman”). Stage incarnation incorporates a number of Glen Hansard and Marketa Irglova’s songs from the film, including Oscar-winning tune “Falling Slowly,” along with additions also penned by the songwriting pair.

Cast, led by Steve Kazee and Cristin Milioti as musicians who fall in love, will move with the show to the Main Stem.

Transfer for “Once” continues to fill out the Broadway season’s lineup of new musicals, a category that had seemed unusually sparse earlier this fall. Along with another recent addition to the spring sked, “Newsies,” “Once” joins a slate of new tuners that also includes current offerings “Bonnie and Clyde” and “Spider-Man: Turn Off the Dark” as well as upcoming offerings “Nice Work If You Can Get It” and “Lysistrata Jones,” which opens next week.

Bob Crowley (sets and costumes), Natasha Katz (lights) and Clive Goodwin (sound) are among the design team of “Once,” produced on the Main Stem by Barbara Broccoli, John N. Hart Jr., Patrick Milling Smith, Frederick Zollo, Brian Carmody and Michael G. Wilson, with Robert Cole on board as exec producer.

Show, which will run at NYTW through Jan. 15, is set to begin previews Feb. 28 ahead of a March 18 opening at the Jacobs.
