Trendspotters, take note. Less than a week after screenwriter J.D. Shapiro manned up and (amusingly) apologized for his part in Battlefield Earth, Monster House screenwriter Dan Harmon is dropping nuts on director Gil Kenan and executive producer Steven Spielberg in an email to a friend, calling the former a “hack” and the latter a “moron.” Movieline has the scoop, which, though a few days old and removed from its original source, is probably still eliciting apologetic emails.
