The Fraggles, the puppet stars of the 1980s children's television series Fraggle Rock, are to star in a movie.
The late Henson directed the films The Dark Crystal and Labyrinth
The Jim Henson Company, which also created The Muppets, is developing a film that will follow the Fraggles on an adventure in the human world.
Co-chief executive Lisa Henson said it was the perfect time for a new Fraggle adventure "celebrating diversity and promoting world peace".
Fraggle Rock was shown worldwide and ran for five series in the 1980s.
"Fraggle Rock has remained a favourite project at our company and has certainly continued to be loved by its many devoted fans, so we are thrilled to begin work on this project," said Ms Henson.
The television series showed the Fraggles' interaction with neighbour creatures the Doozers and Gorgs, promoting messages of mutual respect and peace.
Fraggle Rock was an international co-production adapted to meet the needs of each territory.
The UK version featured a human lighthouse keeper called The Captain, originally played by Fulton Mackay.
