Sheridan Smith, Hugh Bonneville Film David Walliam's Children Novel 'Mr Stink' (PICTURES)

Sheridan Smith has been snapped filming scenes for the BBC One adaptation of David Walliam's children's novel Mr Stink.

Dressed as her character, wannabe MP Mrs Crumb, Smith is seen chasing after an older lady in a mobility scooter.

The Olivier Award-winning actress, who recently starred in ITV's drama Mrs Biggs, playing the wife of great train robber Ronald Biggs, is also known for her roles in Gavin And Stacey and Two Pints Of Lager. Here, she plays the mother of young heroine Chloe who befriends a whiffy tramp in the best-selling children's tale.

She will be joined by comedian Johnny Vegas, playing her husband Mr Crumb in the one-hour film.

Downton Abbey star Hugh Bonneville, recently announced in the lead role of the homeless but refined Mr Stink who goes to live in lonely Chloe's shed, was also photographed in character.

Wearing a scruffy coat and sporting a beard, Bonneville looked a far cry from his period-drama character the Earl of Grantham.

Comedian Walliams will also make an appearance in the show as the prime minister after notably playing an aide to the PM in his hit comedy Little Britain.

The BBC is working with Walliams's production company on the family story, expected to be screened around Christmas.
