In October 2003, producer Bill Kenwright announced that Carey would make her West End debut in The Sleeping Prince, Terence Rattigan's 1956 play that Rattigan then transformed into a movie script. Carey would play showgirl Elsie Marina, a role created on Broadway by Barbara Bel Geddes and on film by Marilyn Monroe. The film, a romantic comedy set in London in 1911 just before the coronation of George V, co-starred and was directed by Laurence Olivier as the Prince Regent of Carpathia.
Carey, whose most recent CD is E=MC2, will release a compilation recording titled The Ballads in January. As an actress, she has appeared in the films The Bachelor, Glitter, Wise Girls and Tennessee. As noted five years ago, Carey is a big fan of Marilyn Monroe who sang a song in The Prince and the Showgirl and bought the iconic blonde bombshell's piano at an auction.
