DreamWorks Animation has optioned rights to “Dinotrux,” an illustrated children’s book that will be developed as a CG-animated film. Deal was for mid-six figures.Written by Chris Gall, the 32-page book takes place in a fictional prehistoric age, when the world was ruled by Dinotrux, creatures that were part trucks, part dinosaurs, with species like the Craneosauraus, Garbageadon and Tyrannosaurus Trux plowing and bulldozing their way across the terrain. The title characters will be talking creatures. Gall is a commercial illustrator who has written three other books. “Dinotrux” will be published in April by Little, Brown. Hotchkiss and Associates brokered the deal for Sterling Lord.
