Michael Bostick, CEO of Walden Media, told The Hollywood Reporter, "Frank has created one of the most original characters in recent memory with the book's hero, Liam... In order to preserve his wildly funny and unique voice, we're thrilled to be working with Frank to develop the film adaptation that will appeal to the whole family."
Cottrell Boyce, the screenwriter behind A Cock and Bull Story, 24 Hour Party People, and other rather non-kid-friendly films, will be adapting Cosmic himself. Cottrell Boyce has worked with a number of high-profile directors, most frequently with Michael Winterbottom. None other than Roger Ebert is a friend and fan; he met the writer on an old CompuServe forum in the early days of the Internet (remember those?), and interviewed him about his unique career and range at length here. You can also read an excellent article by Cottrell Boyce on Roger Ebert's blog from 2008, originally published in the UK paper Guardian, about writing a screenplay.
Walden Media has released a mixed bag of kids' films, with yawn-inducing but financially successful fare like Tooth Fairy and Journey To the Center of the Earth alongside more creative, though less successful, ventures like City of Ember and Nim's Island. Hopefully, Cosmic will combine the best of both worlds and be both as unique and cool as Cottrell Boyce's other projects and earn the BO to go with it.
