The Land Before Time (Disney Version)

The Land Before Time is a 1988 animated adventure drama film directed and produced by Don Bluth from a screenplay by Stu Krieger and a story by Judy Freudberg and Tony Geiss, and executive produced by Steven Spielberg, George Lucas, Kathleen Kennedy, and Frank Marshall. The film stars the voices of Gabriel Damon, Candace Hutson, Judith Barsi and Will Ryan with narration provided by Pat Hingle. It is the first film in The Land Before Time franchise.

Produced by Amblin Entertainment and Sullivan Bluth Studios, it features dinosaurs living in prehistoric times. The plot features a young brown Apatosaurus named Littlefoot, who ends up alone after his mother is attacked by a villainous Tyrannosaurus rex and dies. Littlefoot flees famine and upheaval to search for the Great Valley, an area spared from devastation, where the adult dinosaurs have moved on to. On his journey, he meets four young companions: Cera, an orange Triceratops, Ducky, a green Saurolophus, Petrie, a brown Pteranodon, and Spike, a green Stegosaurus. The film explores issues of prejudice between the different species and the hardships they endure in their journey as they are guided by the spirit of Littlefoot's mother and forced to deal with a "sharptooth" (Tyrannosaurus rex).

The Land Before Time is the only Don Bluth film of the 1980s in which Dom DeLuise did not participate (instead, he starred in Disney's Oliver & Company released that same day), and the only film in The Land Before Time series that is not a musical, as well as the only one to be released theatrically worldwide. It was also the last film that Bluth directed that was distributed by Walt Disney Pictures.

The film was released by Walt Disney Pictures on November 18, 1988, to generally positive reviews from critics and was a box office success, grossing $84.4 million. Its success, along with An American Tail and the 1988 live-action/animated film Who Framed Roger Rabbit led Spielberg to found his animation studio, Amblimation. The first film spawned a franchise with thirteen direct-to-video sequels, a television series, video games and merchandise, none of which had Bluth, Spielberg nor Lucas' involvement (though Amblin Entertainment was involved in the television series like it was for Fievel's American Tails). It is currently Don Bluth's third highest-grossing animated film, only behind Anastasia (1997) and An American Tail (1986).
