Enid Blyton's classic children's stories The Famous Five are to be transformed into a modern animated TV adventure series.
The Famous Five books have never been out of print
The series will be based on Blyton's original books about Julian, Dick, Ann, George and Timmy the Dog, but will be given a 21st century setting.
Blyton's books, which were written between 1942 to 1963, continue to sell 450,000 copies each year in the UK.
The cartoon series is expected to air in early 2007.
An initial 26 episodes will be made of the adventures as the children go about solving mysteries.
The rights to Blyton's books are owned by entertainment group Chorion, which hopes to sell the cartoon series around the globe.
Chorion chair Lord Alli said: "The Famous Five represent the heartland of Blyton for generations of young readers throughout Europe.
"I am delighted that we will be making an animated television series that will allow us to introduce the characters to an even wider global audience."
The first Famous Five book, called Five on a Treasure Island, was published in 1942.
They were made into a TV series, starting in 1957, with the most recent filmed in 1996.
