Rebecca Caine is a Canadian opera and musical theatre performer.
Caine was born in Toronto and studied at the Guildhall School of Music and Drama in London. She is the daughter of Australian statistician Geoffrey Watson and the granddaughter of British constitutional law scholar Sir William Ivor Jennings. Caine currently resides in London.
Caine’s career has been divided between opera and musical theatre. She made her West End debut at the age of 19 in the role of Laurey in Oklahoma!. She then sang the role of Eliza in My Fair Lady on a national tour. While making her debut at Glyndebourne as Amor in L'incoronazione di Poppea, she was asked to join the Royal Shakespeare Company where she created the role of Cosette in Les Misérables.
After a successful West End run, she joined the original cast of Phantom of the Opera to play Christine opposite Michael Crawford as alternate (performing 2 shows a week) when original Christine Sarah Brightman left the show and was replaced by the original alternate, Claire Moore.
When the rights to a Canadian production of Phantom were secured, producer Garth Drabinsky aggressively pursued Caine to reprise the role in Toronto. Andrew Lloyd Webber, who greatly admired Caine's portrayal of Christine in the London production, also strongly suggested she take the role. At the time, Caine was very close to signing a contract to star in another West End show. Ultimately, she chose Phantom and relocated to Toronto and also spent time in New York in early 1989 for principal cast rehearsals with director Hal Prince.
