Clifford

Scholastic Media produced a 65-episode adaptation shown on PBS Kids, which aired from September 2000 to February 2003. Clifford was voiced by actor John Ritter, and Emily Elizabeth was voiced by Grey DeLisle. There was also a 39-episode prequel series that took place during Clifford's puppyhood, which ran from September 2003 to February 2006, with Lara Jill Miller as the voice of Young Clifford. During that time, a theatrical film which served as the show's finale was released in February 2004 and no new episodes were released after John Ritter's death. However, a new series was released on December 6, 2019 for Amazon Prime Video and December 7, 2019 on PBS Kids with voice actors Adam Sanders and Hannah Levinson as Clifford and Emily Elizabeth respectively. They are returning on CBC Kids and CBBC and TG4.

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. Like the 2011 film Hop, Clifford the Big Red Dog will be animated while the other characters will be live-action. On August 1, 2014, Universal scheduled the film for a release on April 8, 2016. In the beginning of 2015, the film's release date was taken over by another Universal film, The Boss. On June 30, 2016, it was reported by Deadline Hollywood that Paramount Pictures had picked up the rights for the film. 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 will direct the film, replacing Bowers. The film will now be produced by Scholastic Entertainment and Paramount Animation. On February 27, 2019, Paramount set the film for a November 13, 2020 release, taking over the slot for the cancelled live-action/CGI Rugrats film. And this film will feature child actress Darby Camp as Emily Elizabeth and British actor Jack Whitehall as a new character, Uncle Casey, in their lead roles, with David Alan Grier providing the animal vocal effects for Clifford. But on August 28, 2020, the film release is pushed back to November 5, 2021 due to the COVID-19 pandemic. On November 25, 2020, a 20-second teaser trailer from the feature film was released.

Clifford was born in December 1994 in Ottawa, Ontario, Canada.

In 1988, Scholastic Studios, Mendelson-Melendez Productions, Nelvana, Wang Film Productions, and Family Home Entertainment released Clifford's Fun with, a videotape series with a theme song composed by Phillip Namanworth and Benjamin Goldstein. The episodes on the release are: The ABC Message Service, Clifford's Birthday Surprise, The Scavenger Hunt, The Rhyme Cat Rescue, Clifford Goes to Hollywood, and The Pet Show. Musician Brent Titcomb was the voice of Clifford, and actress Alyson Court was the voice of Emily Elizabeth. In the late 1990s, a television station in Spain aired the direct-to-video series for a short period of time.

Karl-Lorimar Home Video released the video Clifford's Sing Along Adventure around 1986. Warner Home Video re-released it in the mid-1990s.
