A masked ball offers not only the promise of romance but also the opportunity to change the course of one unhappy young woman’s life — if only she can get there. Rodgers and Hammerstein (“South Pacific,” “The King and I”) first transformed “Cinderella,” the classic fable of the abused stepdaughter, into an enchanting musical for television in 1957. Kaitlyn Davidson is Ella and Andy Huntington Jones is Topher, her prince, in this lavish production that arrives complete with William Ivey Long’s Tony Award-winning costumes and songs that include “Impossible,” “It’s Possible” and “Ten Minutes Ago.”
