Sullivan was recently featured in the TV reality casting show "I'd Do Anything" to find an actress to appear as Nancy in the forthcoming revival of Oliver!, while Dobinson was one of the finalists for BBC's "How Do You Solve a Problem Like Maria?" search for the star of the current West End production of The Sound of Music. Sullivan was recently seen on tour in the original cast of Never Forget, and Dobinson previously appeared in Les Misérables as a child actress, when she played young Eponine.

In a press statement, producer Cameron Mackintosh commented, "It is very exciting to see new talent coming into the West End at the moment. Thanks to Andrew Lloyd Webber and the success of BBC television programmes such as 'How Do You Solve a Problem Like Maria' and 'Any Dream Will Do,' new audiences are coming to the theatre. These programmes have also helped unearth some tremendous talent, many of whom have gone on to star in many other West End productions. Although both Nancy and Leanne may have missed out on the respective roles they were vying for in these shows, their talents did not go unnoticed. I was delighted to give them the chance to win parts in Les Misérables which I'm sure they will be terrific in. I also recently cast Daniel Boys, one of the Joseph finalists in BBC's 'Any Dream Will Do,' in Avenue Q where he has enjoyed great success. Katie Hall, who [was] featured in early episodes of 'I'd Do Anything,' has also recently been cast in the ensemble of The Phantom of the Opera – where she will have the opportunity to cover the role of Christine."
