Cars is the second Pixar film to have a sequel (the other one being Toy Story). Cars 2 originally was scheduled for a 2012 release, but Pixar moved the release forward a year. It is the first of two films that Pixar will release in 2011 (the second being The Bear and the Bow), marking the first time that the studio will release more than one film in the same year.
By late 2008, three cast members of the original Cars had died; Joe Ranft (Red) was killed in a road accident in 2005, during the production of the first film, George Carlin (Fillmore) died of heart failure in June 2008 and Paul Newman (Doc Hudson) died three months later after losing an ongoing cancer battle. No announcements have been made as to whether the roles will be recast or simply written out of the sequel.
