However, this was deemed impractical due to budgetary concerns of using computer generated monsters as main cast members in a live-action production, and as a result he instead turned the idea into a book he co-wrote alongside Daniel Kraus and published by Disney-Hyperion.

The project attracted an all-star cast, including the voices of Anton Yelchin, Emile Hirsch, Mark Hamill, Kelsey Grammer, Ron Perlman, Glenn Close, Lena Headey, Steven Yeun, Anjelica Huston, Diego Luna, Nick Offerman, Tatiana Maslany, Nick Frost, Stephanie Beatriz, Alfred Molina, David Bradley, Colin O'Donoghue, John Rhys-Davies, and more throughout its six year run.
