BBC Worldwide, the commercial arm of the BBC, is working on a theatrical version of its acclaimed natural history documentary series The Blue Planet.

BBC Worldwide has signed a co-production agreement with German production and international distribution company Greenlight Media to fund the feature length documentary.

Greenlight Media will co-ordinate all global sales activities in regard to the TV and video/DVD rights of the film in conjunction with BBC Worldwide.

The theatrical version of The Blue Planet is billed as 'more than just a natural history spectacle,' and described as ' an emotive 90-minute roller-coaster tour of the oceans.' Academy Award-nominated composer George Fenton is re-scoring the soundtrack and with minimum narration, the film will be a totally 'immersive' experience.

Alix Tidmarsh, Director of IPM Factual - the factual marketing division of BBC Worldwide - commented: "Greenlight Media's experience makes them the ideal partner to secure the funding we need to get this movie made."

Over 12 million people watched The Blue Planet, which was narrated by David Attenborough, when it aired on BBC1 in the UK in 2001. It has since sold to over 50 countries.
