Here's why it's unlikely:
* The Last Straw is already adapted: "The Last Straw" was the third book in the series and was adapted into a movie back in 2011.
* Focus on new stories: Recent Diary of a Wimpy Kid movies (both live-action and animated) have focused on adapting newer books in the series, like "Diper Överlöde" and "Dog Days."
* Jeff Kinney's involvement: Author Jeff Kinney has been actively involved in the recent adaptations, and he seems to be prioritizing stories from later in the book series.
While a "The Last Straw" remake isn't completely out of the question, it's not something that's been discussed or planned.
