Bierko, who succeeded Olivier Award winner and Tony nominee Bertie Carvel, was originally scheduled to begin performances as the evil school mistress Sept. 3. A shoulder injury delayed the start of his engagement to Sept. 17.
The role, which requires the actor to perform a series of gymnastic routines in the second act, has aggravated Bierko's injury. He will be taking a 12-week disability leave from the Tony-winning production.
Tony Award-winning director Matthew Warchus (God of Carnage, The Norman Conquests, Boeing-Boeing, La Bête, Ghost) staged the inventive, kid-packed musical that has a book by Dennis Kelly and a score by Tim Minchin. It opened on Broadway April 11.
An original Broadway cast album will be released in the coming months. Matilda received four Tony Awards, including Best Book of a Musical, Best Featured Actor (Gabriel Ebert), Best Lighting Design and Best Scenic Design.
The U.K. hit premiered at the Royal Shakespeare Company's Courtyard Theatre in November 2010 and later transferred to the West End's Cambridge Theatre, where it continues to run. The Royal Shakespeare Company and The Dodgers present the Broadway run.
The Broadway principal company also features Olivier Award winner Lesli Margherita (Zorro; Kiss, Me Kate) as Miss Wormwood, Gabriel Ebert (4000 Miles) as Mr. Wormwood, Jill Paice (Curtains, The Woman in White) as Miss Honey and veteran Chicago actress Karen Aldridge ("Boss," "Chicago Fire") as Mrs. Phelps. Young British actor Ted Wilson from the original London cast of Matilda repeats his work as schoolmate Eric in the Broadway production.
The Matilda ensemble includes Frenie Acoba, Erica Barnett, Judah Bellamy, Jack Broderick, Ava DeMary, John Arthur Greene, Emma Howard, Nadine Isenegger, Colin Israel, Thayne Jasperson, Luke Mannikus, Madilyn Morrow, Sawyer Nunes, Jared Parker, Celia Mei Rubin, John Sanders, Tamika Sonja Lawrence, Phillip Spaeth, Ryan Steele, Betsy Struxness, Samantha Sturm, Heather Tepe, Ben Thompson, Clay Thomson, Taylor Trensch and Beatrice Tulchin.
According to producers, Matilda "is the story of an extraordinary little girl who decides that despite a bad beginning filled with rotten parents, a terrifying school and a vicious head mistress, her story is going to be an astonishing one. With the help of her teacher, her friends and a little bit of imagination, Matilda proves that even if you're little, you can do big things."
The production has set and costume design by Rob Howell, with choreography by Peter Darling, orchestrations, additional music and musical supervision by Christopher Nightingale, lighting design by Hugh Vanstone and sound design by Simon Baker.
