Art of Pixar Short Films author Amid Amidi contacted me this morning to inform me that he is "no longer writing The Art of Toy Story 3" for Pixar and Chronicle Books —a tremendously surprising development.
When asked about the reasons why, Amid did not wish to comment any further. I suspect there was a falling-out of some nature, but have no supporting facts except the lack of rationalization in his comments.
Amid had earlier tried to comment briefly about the change on my interview with Tim Hauser for The Art of Up since his work on The Art of Toy Story 3 was discussed in the Q&A. I rejected his comment thinking it was not genuine and so he emailed me at firstname.lastname@example.org to let me know that it was.
