The first Pixar film to be presented at Disney’s D23 Expo on Friday during the studio’s portion of the animation panel was The Good Dinosaur. Peter Sohn (Partly Cloudy) makes his feature directing debut on Pixar’s first prehistoric film about Arlo, an apatosaurus who becomes separated from his family, and sets off on a journey that will make him grow stronger physically and as a dinosaur.

In The Good Dinosaur, our lead character Arlo is not as strong as his dinosaur siblings, drawing his strength from his father. Unfortunately, his father passes on, and we learn that Arlo eventually becomes separated from his family. The clip that was shown reveals the treacherous waters that nearly drown him. Luckily, he is able to be washed ashore, where he eventually comes across a human named Spot.

Pixar’s The Good Dinosaur has had its share of production problems in the past. The first sign of trouble was when Bob Peterson was a no-show at D23 Expo in 2013. Due to some issues with the story, Peterson was taken off the project, and replaced by Peter Sohn (Pixar animated short Partly Cloudy). At the time, the film had already cast its voice talent, which consisted of Lucas Neff (Raising Hope), John Lithgow, Frances McDormand, Neil Patrick Harris, Judy Greer, and Bill Hader.

But we are now learning that The Good Dinosaur is getting a major voice cast overhaul, and everyone except McDormand has been replaced. Some of the incoming talent includes, Anna Paquin, Sam Elliott, Jeffery Wright, Steve Zahn, and more. Check out the new cast below.

Pixar’s The Good Dinosaur was originally slated for a 2014 release. But problems with the story forced the film’s original director, Bob Peterson, out, and pushed the film back to a November 2015 release. The first signs of trouble started to appear when Peterson was noticeably absent at the D23 Expo in 2013.

Since then Peter Sohn came on board as director to resolve some of the story issues that The Good Dinosaur was suffering from, and in a new report from The LA Times, we are getting a better understanding of why the film had to be pushed back, and what he has done to fix some of the problems.

It’s time to scare it up, my fellow geeks! Monsters University sees its home release, and surprisingly, the Blu-ray edition of Pixar’s latest feature is wicked good. Explore Monsters University with me, shall we?

James P. Sullivan (John Goodman) and Mike Wazowski (Billy Crystal) may have given the impression they were always best buddies in Monsters, Inc., but Monsters University proves just the opposite. Travel back in time with Sulley and Mikey to their young adulthood, when Sulley’s pomposity and Mike’s unabashed idealism contrasted with their older personalities. Mike craves to scare for a living, despite his less-than-menacing appearance, and must prove to naysayers that he belongs at the Scare School. He works ceaselessly to understand ways to haunt and chill. Sulley, on the other hand, thinks his family name and reputation will lead him on a road to success, but his egotism impairs his image and potential. The two must collaborate with the non-impressive Oozma Kappa fraternity to save their spots in the Scare School.

The first teaser trailer for Disney*Pixar’s prequel to the 2001 hit Monsters Inc., titled Monsters University, has been released online.

In the movie, Mike (Billy Crystal) and Sully (John Goodman) are back in college, and they may not have started as the best of friends. The teaser shows off one of the college pranks Sully pulled on Mike…surely the first of many we’ll see between the two.
