Walker Productions - part of international children's publisher Walker Books - has sealed a development agreement with Ireland-based JAM Media and Polly Dunbar, the author of pre-school series Tilly and Friends.
The deal is part of ongoing plans for Walker Productions to develop Walker-owned content for other media platforms.
For JAM Media, this will be its first development deal outside of its own ideas.
"We are very excited to be working with such fantastic partners on this project," said Michael Dee, development director at Walker Productions. "Tilly and Friends is a beautifully illustrated, engaging and interactive series, and we look forward to developing the characters for the screen. The Tilly and Friends series has enormous potential as a property."
Tilly and Friends - a six book series aimed at pre-schoolers - launched last year with Hello Tilly and Happy Hector. A further two books arrive this month, with the final duo set to arrive in the autumn.
Publishers in France, Germany, Norway and Japan have all signed up the series, with more deals due to be announced shortly.
