Lesley Sharp and Marc Warren are well-known television actors
Actors Lesley Sharp and Marc Warren are to co-star with X Factor finalist Diana Vickers in the West End revival of The Rise and Fall of Little Voice.
Sharp, whose screen credits include Cranford, Medium and Clocking Off, will play LV's wayward mother Mari.
Warren will portray small-time club promoter Ray Say. The actor starred in four series of Hustle as Danny Blue.
The play, about a girl able to mimic stars such as Judy Garland, opens at London's Vaudeville Theatre in October.
Producer Nica Burns said: "When Marc and Lesley first walked on stage together, the chemistry between them was instant."
She added that 18-year-old Vickers, who came fourth in last year's X Factor behind winner Alexandra Burke, is "our perfect Little Voice".
Little Voice suffers at the hands of her overbearing mother
The singer is taking a break from recording her debut album to star in the show, which is being staged for a limited period.
It portrays the talents of the vulnerable Little Voice, who is exploited for gain by her mother and latest boyfriend Ray Say.
The play, by Jim Cartwright, was originally staged at the National Theatre in 1992 and was nominated for six Olivier awards.
It was adapted for the big screen seven years later, and starred Jane Horrocks as LV, with Brenda Blethyn as her mother and Sir Michael Caine in the role of Ray Say.
Ewan McGregor also starred in the film as pigeon-fancying Billy, who will be played by actor James Cartwright in the new production.
