Diary of a Wimpy Kid: Dog Days is a 2012 American comedy film directed by David Bowers from a screenplay by Wallace Wolodarsky and Maya Forbes. It stars Zachary Gordon and Steve Zahn. Robert Capron, Devon Bostick, Rachael Harris, Peyton List, Grayson Russell, and Karan Brar also have prominent roles. It is the third installment in the Diary of a Wimpy Kid film series, and is based on the third and fourth books in the series, The Last Straw and Dog Days.
The film was released on August 3, 2012. It is also Bowers' second live-action film. Although the film is based on the third and fourth Diary of a Wimpy Kid books, there is a scene based on the first book, where Greg's dad, Frank, is trying to unplug Greg's video game system, but does not know how to. There's also a scene based off the second one, where Greg is sick on picture day, and his second grade picture gets sent in. Unlike the book, Greg was the one who was sick, where in the book, it was Rodrick.
Diary of a Wimpy Kid: Dog Days is also the last film in the series to feature the original cast members, as many of the cast (such as Zachary Gordon, Robert Capron and Devon Bostick) outgrew their roles and a re-cast was made for the future films in the series, starting with Diary of a Wimpy Kid: The Long Haul, which was released five years later.
