The NHS Choir have signed a Hollywood film deal to tell their story of success.
The Lewisham and Greenwich choir gained fame when they beat Canadian pop star Justin Bieber to score the coveted Christmas number one spot last year.
British producer Julia Verdin, whose past credits include The Merchant Of Venice starring Al Pacino and 2 Jacks which featured Sienna Miller, has secured the rights to tell their story.
The movie will feature the individual back stories of the 32 choir members and the work they do, documenting their journey to get their song A Bridge Over You to the top of the charts.
Their plight was helped when Justin tweeted his 80 million Twitter followers, telling them to "do the right thing" and help the choir reach the top of the singles chart.
Choir co-ordinator and children's physiotherapist Caroline Smith said: "We are thrilled that the world will now get to see our incredible story. People will see the massive power achieved when everyone comes together'."
Julia said: "I believe people will love watching this remarkable and uplifting story which has already touched the hearts of millions in the UK."
The choir's debut album, Something Inside So Strong, will be released on June 3 by Universal, who represent the likes of their Christmas chart rival, Justin.
Royalties will be paid into the Lewisham and Greenwich NHS Trust and will be used to provide services that "enhance patient experience or staff working lives".
