Mike Bender ("Bob the Musical", "Not Another Teen Movie") has been hired to write the adaptation about the trials and tribulations of a young boy who is experiencing one of his worst days ever.

Neal Moritz will produce. The book has sold more than two million copies, collected many awards, and kicked off a series of "Alexander"-themed books.
