Ranking the top Pixar movies . THE GOOD DINOSAUR . Pixar 's 2014 film about a world where dinosaurs never went extinct will feature an Apatosaurus family who work as farmers tilling fields to grow tree crops to feed their herbivore brethren . Poppa and Momma will be voiced by John Lithgow and Frances McDormand , while Bill Hader voices the older brother Forrest . Neil Patrick Harris and Judy Greer will play middle-sibling dinosaurs Cliff and Ivy , and the lead character — baby brother Arlo — will be performed by `` Raising Hope '' 's Lucas Neff . Pixar showed off the first footage , tracking a humongous potato-like asteroid as it hurdles through deep space on a collision course with Earth 65 million years ago , and ... Misses . A few prehistoric dinosaurs munching on some midnight snacks look up to see a blue bolt shoot across the sky and disappear . Director Bob Peterson ( a veteran story artist with the company , and the voice of Dug the Dog from `` Up '' and growling Roz from `` Monsters Inc. '' ) oversees the film with co-director Pete Sohn ( who voiced mama 's boy Squishy in `` Monsters University . '' ) `` The modern dinosaurs are farmers , '' Sohn said . `` We actually designed them to function as their own farm equipment . '' Triceratops are bulldozers , the stegosauruses `` have spiky tails that mow down acres of crops , '' and the Apatosaurus uses its long neck and tough bill to plow and plant the fields . While working the field one day , Arlo discovers a large beetle rustling around the ground , but there 's something strange about it . It 's actually a human toddler , in disguise . He 's a grunting , savage little boy named Spot — who ca n't talk like the dinosaurs around him . `` Spot is all alone in the world , '' Sohn said . `` He 's not afraid of anyone -- even a dinosaur 20 times taller than him . '' The film explores what happens when dinosaurs , the dominant species on Earth , discovers these strange , clever pests we would call humans . No images were immediately released , but for now we have this piece of concept art — featuring an evolved , long-necked dinosaur ( most likely Arlo ) cutting the clouds while running through a mountainside plain .

When Lasseter revealed this project two years ago at the last D23 event , it was called simply `` Pixar 's Untitled Project That Takes You Inside the Mind . '' Now it 's known as `` Inside Out , '' a comedy from `` Up '' director Pete Docter and producer Jonas Rivera — and D23 finally revealed some plot details for the 2015 movie .

Riley , the once happy-go-lucky pre-teen is uprooted from her pleasant life in Minnesota and thrust into a new , unwelcome existence in San Francisco . That 's when the emotions take over , much to the chagrin of her baffled parents . Anger ( Lewis Black ) , Disgust ( Mindy Kaling ) , Fear ( Bill Hader ) , Sadness ( `` The Office '' 's Phyliss Smith ) and Joy ( Amy Poehler ) spar , collaborate , and miscommunicate with one another in an attempt to keep her functioning . `` We get to take you places everyone has thought about but nobody has seen before . Places like 'long-term memory , ' '' said Docter . Other places visited include the Disneyland-esque Imaginationland and `` Abstract Thought , '' where emotions become Piccaso-style versions of themselves .
