The Broadway production
The Broadway League's production record dates Frozen's opening at the St. James Theatre to March 22, 2018. It credits a book by Jennifer Lee and music and lyrics by Kristen Anderson-Lopez and Robert Lopez. The musical adapts the Disney film for live actors, a theatre stage and a different performance format.
The same record lists the original Broadway run through March 11, 2020. That is the history of a particular production, rather than the schedule of every touring, licensed or international staging of Frozen.

Disney's March 2018 trailer article highlighted new songs, costumes, sets, staging and dance, including the song Monster performed by Caissie Levy as Elsa. These elements help explain why a stage adaptation is more than a screening of the animated movie.
Before arranging a visit, check the named venue, city, performance date and official ticket source. An old article establishing that a musical exists cannot establish current availability in your city. The related Movies section provides coverage of screen productions, while this page keeps the stage adaptation's history distinct.
