Creator Jeff Kinney originally announced a Diary of a Wimpy Kid animated series. For unknown reasons, it was changed into a new animated movie.
Unlike the live-action adaptation, Angie does not exist in this movie. Patty also does not appear in the film who is only mentioned once by Rowley.
According to the credits of this movie, Holly's friend makes an appearance. But Holly herself does not.
A scene in the teaser showed Greg pushing a huge ball of snow. This scene was not used.
Has a similar animation style to that of The Peanuts Movie (2015) and Captain Underpants: The First Epic Movie (2017).
