Lord Lloyd-Webber will produce The Wizard Of Oz in London's West End
Lord Lloyd-Webber's latest Saturday night talent show will search for a girl to play Dorothy and a dog to play Toto in The Wizard Of Oz, the BBC says.
Winners of the programme will star in a West End production of the musical.
It follows BBC One's I'd Do Anything, Any Dream Will Do and How Do You Solve A Problem Like Maria? which also found musical stars.
The new programme, also called The Wizard Of Oz, will again be presented by Graham Norton.
Lord Lloyd-Webber, 61, said the previous talent shows he had made with the BBC had "provided an incredible shot in the arm for musical theatre in Britain".
Jodie Prenger won the role of Nancy on I'd Do Anything last year
"I can't wait to work with the BBC again in the hunt for Dorothy - an iconic role of course made famous by a young Judy Garland in the film in 1939," he added.
"But, as a cat man myself, however, I approach casting Toto with considerable trepidation."
The search for Dorothy will begin with auditions across the UK in early 2010 with the programme airing later in the year.
Lord Lloyd-Webber's fellow judges have yet to be announced.
