Speaking to the Daily Mail, Ryan described the role as a "gift", adding: "Sally is quite delusional. She’s not the best singer, she’s not a performer, but she has this kind of spirit that takes her through it all ... I’ve been working with a voice coach for two years (on new film The Man Inside), so you could say that when Cabaret came along I was ready."
Based on the stories of Christopher Isherwood and the play by John Van Druten, Cabaret has a book by Joe Masteroff, music by John Kander and lyrics by Fred Ebb. It premiered on Broadway in 1966 and in 1972 was made into an Oscar-winning film starring Liza Minnelli as Sally Bowles, Michael York as Cliff and Joel Grey as the Emcee.
Norris’ Olivier Award-winning production originally opened at the West End’s Lyric Theatre in October 2006 with James Dreyfus as the Emcee and Anna Maxwell Martin as Sally, who was later succeeded by Kim Medcalf.The production, which is choreographed by Javier de Frutos, will play a four-week UK tour before opening at the Savoy.
Since rising to fame in EastEnders, Ryan, now 28, has appeared in TV series including Jekyll, Bionic Woman, Merlin and Doctor Who, while her stage acting credits include Toby Young's Who's the Daddy? at the King's Head (2005) and The Talented Mr Ripley at the Royal and Derngate, Northampton (2010).
