Filming has now started on a movie version of the story of 11 Women's Institute members who made thousands of pounds for charity when they stripped naked for a charity calendar.

Helen Mirren, Julie Walters and Penelope Wilton are among the star names featuring in the tale of the Yorkshire Dales-based group, which hit the headlines four years ago.

Their calendar sold more than 80,000 copies when their story went round the world.

Rylstone WI raised more than £500,000 for Leukaemia Research and the idea was copied by countless voluntary groups and sports clubs across Britain.

The story of the women is being filmed on location in the Yorkshire Dales, starting in the village of Burnstall, near Bolton Abbey, then moving to London and Los Angeles

The movie is due for release next year.
