A production spokesperson said a celebration will be held on a later date.
Based on the Roald Dahl novel "Matilda," the show tells the story of an unusually bright little girl who refuses to be ground down by parents who despise her or by a cartoonishly evil school headmistress named Miss Trunchbull who is determined to break her spirit. With the help of her kindly schoolteacher Miss Honey, Matilda uses her intelligence, her love of books and a mysterious secret super power to prevail over those who would repress her.
Matilda has music and lyrics by Tim Minchin and book by Dennis Kelly. It opened in London in 2011 and is still running there as well. The Broadway version opened April 11, 2013, at the Shubert Theatre.
