This year’s D23 Expo in Anaheim, CA, is kicking into high gear, especially with the start of the massive event today focusing on animation. At the Pixar Animation Studios portion of the event, Finding Nemo director Andrew Stanton and producer Lindsey Collins emerged from behind the stage to discuss the sequel to everyone’s favorite fish film, Finding Dory

Major vocal casting announcements were shared. Joining the returning Ellen DeGeneres (Dory) will be Diane Keaton as Jenny, Dory’s mom, whereas Eugene Levy will bring life to Charlie, Dory’s dad. Ty Burrell will voice Bailey the Beluga Whale. After Stanton announced Bill Hader will not appear in the film, the comedian came out, dressed as a sea cucumber.

Apparently Hader wants to voice a character in more than just a handful of films. He wants to be a lucky charm. Not so fast, Hader, as John Ratzenberger (Toy Story) came out with the Disneyland marching bad – much to Hader’s dismay. This skit was quite funny, and showcased a nice comedic dialogue between the two. “You’ve Got a Friend In Me,” the popular tune from Toy Story, played them out.

Stanton said he has been asked for years to develop a continuation to the Academy Award-winning Finding Nemo, but hadn’t developed the right storyline. Then he wondered where Dory’s family was, so the sequel, which takes place a year after the end of Nemo, will reunite the forgetful blue tang fish with her family members, with a storyline set in part along the California coastline.

At the Expo, we were shown a few pieces of concept art of Dory in this sequel that explores a traumatic event that causes the Regal Blue Tang to search for her roots (see one piece shown here above). What that traumatic event is, we don’t know yet. Dory embarks on an amazing adventure, where she meets many creatures, including an otter from what the concept art looked like.

Finding Dory comes to theaters November 25, 2015.
