Clifford the Big Red Dog is an American children's book series and media franchise focusing on the adventures of 8-year-old Emily Elizabeth and her titular, gigantic, love-filled, red-furred pet dog. It was first published in 1963 and was written by Norman Bridwell. There are 91 books in the series, with the final two released posthumously after Bridwell's death in 2014. The premise has been adapted into animation, video games, stage productions, and live-action, with the 2021 film being the most recent as of 2026. Clifford is the official mascot of Scholastic Corporation.

Concept and creation The character was inspired by author Norman Bridwell's childhood desire to own a dog the size of a horse. In 1962, Bridwell included paintings of what would become Clifford the Big Red Dog (named 'Tiny' at the time) in a portfolio of children's literature illustrations. In the process of showcasing his portfolio for publishing houses, Susan Hirschman at Harper & Row suggested Bridwell turned his drawings into a children's story. Bridwell then developed a story around the dog and his owner, which he would eventually submit to Scholastic. His wife suggested the name "Clifford" after her imaginary friend from her childhood, and Emily Elizabeth was named after Bridwell's daughter. The first book in the series was originally published by Scholastic in 1963.

Characters

Clifford is a male red dog whose appearance, disposition and behavior are based on that of a giant dog. The depiction of Clifford's size is inconsistent. The character's name is based on the imaginary childhood friend of Norman Bridwell's wife, Norma Bridwell. Bridwell originally wanted to name the dog "Tiny", but his wife persuaded him that "Clifford" was better. Clifford's pet owner is Emily Elizabeth. Clifford has a mother, two brothers, and two sisters, all of whom are normal-sized dogs. Clifford was originally the runt of the litter, seemingly fated to be small and sick, but grew to an enormous size apparently due to Emily Elizabeth's love and care. Clifford's character was created when a Harper & Row editor advised Bridwell to write a story to go along with one of his pictures. Bridwell recalls she picked out his sketch of a baby girl with a horse-sized bloodhound, and casually said, "There might be a story in this" because there always was one. Emily Elizabeth is an 8-year-old girl with blond hair. She is Clifford's owner and human friend, frequently portrayed riding him like a horse. She was named after Bridwell's daughter and based on the imaginary adventures of Bridwell's wife. The TV series adaptation gives her a surname, Emily Elizabeth Howard, and changes the background, with her receiving Clifford as a surprise present on her 6th birthday instead of picking him out as a Christmas present.

Films

2004 film

During the 2000 series' run, a theatrical film was released in February 2004, serving as the series finale, as there were no new episodes released after John Ritter's death the year prior.

Unproduced Universal-Illumination version In May 2012, it was reported that Universal Pictures and Illumination Entertainment would make a live-action/CGI animated feature film based on the book. Matt Lopez had been hired to write the script, while Chris Meledandri and Deborah Forte would produce the film. In July 2013, it was reported that Illumination had dropped the project. Two months later, it was reported that the film was still in development at Universal and that there were negotiations to have David Bowers direct the film.

On August 1, 2014, Universal scheduled the film for a release on April 8, 2016, later to be delayed and its release date given to The Boss. On June 30, 2016, it was reported by Deadline Hollywood that Paramount Pictures had picked up the rights for the film and the Universal iteration cancelled. According to the report, "Forte decided to take the material in a new direction," and "Universal let the option lapse." It was further announced that Justin Malen was hired to write the screenplay.

On September 25, 2017, it was announced that Walt Becker would direct the revived project, replacing Bowers."7 Days of Deals", The Hollywood Reporter, 27 September 2017, page 30. The Paramount iteration, which would eventually turn into the finalized film, was produced by Scholastic Entertainment and Paramount Animation.

2021 Paramount film

On February 27, 2019, Paramount announced the film for a November 13, 2020 release, taking over the slot for the cancelled live-action/CGI Rugrats film. The film features child actress Darby Camp as Emily Elizabeth and Jack Whitehall as a new character, Uncle Casey, in their starring roles with Tony Hale as Zac Tieran, the main villain of the film. On August 28, 2020, the film release was pushed back to November 5, 2021, due to the COVID-19 pandemic, with a 20-second teaser trailer released in November that year. The film was subsequently rescheduled to be released on September 17, 2021, but was again delayed due to concerns regarding the rise of the SARS-CoV-2 Delta variant. The film premiered as a part of Paramount's Upcoming Slate Presentation at CinemaCon on August 26, 2021; the film later released theatrically and digitally on Paramount+ on November 10, 2021.
