After a short-lived stint with live-action films, Andrew Stanton returns home to direct Finding Dory, a sequel to the fan favorite Finding Nemo. Angus MacLane (Toy Story of Terror) joins him as co-director. Rather than just have another story about a missing fish, the follow-up changes a few things up by making Dory go missing after realizing that she got separated from her family after being hit with short-term memory loss. Ellen DeGeneres and Albert Brooks will reprise their voice roles as Dory and Marlin respectively, with Hayden Rolence replacing Alexander Gould as Nemo.

During the Walt Disney Animation Studios presentation at the D23 Expo on Friday, we learned that Finding Dory will be adding Ty Burrell (Modern Family) as Bailey, a beluga white whale, Ed O’Neill (Modern Family) an octopus with a missing arm, and Kaitlin Olson (Always Sunny in Philadelphia) as a whale shark. More here below on their characters plus a description of the footage that was shown at the panel.

The first clip starts with Dory awakening from a concussion while on a school trip. Thinking that she is fine, Marlin and Nemo take her to her coral reef home. However, what was suppose to be a good night sleep turns into her sleep swimming while muttering the jewel of Monterey Park. She isn’t aware of what she is saying until she is hit with a vision of her loving parents caring for her, and it is then that she realizes that she has to go home across the Pacific.

Hesitant at first, Marlin is convinced by his son to go along with Dory on her journey home, reminding him about trying to find family. Questioning whether or not he can take them across the ocean, Marlin says to the two that he knows a guy.

Before we get to see the next clip we are introduced to Bailey, Hank, and Destiny.

Bailey (Burrell) is a beluga whale who thinks that the large bump on his head is the reason why he is at the Monterey Marine Line Institute. Hank (O’Neill) is an octopus who has rehabilitated and is about to be set free in the ocean. Then there is Destiny (Olson), a whale shark who thinks she is more whale than shark.

In one final clip from the film, Dory is accidentally scooped up by institute staffers and put into a seperate tank, and tagged by a marine biologist. It is there that she meets Hank, who had hid himself from the biologists in an attempt to get near the next aquatic animal to be tagged. What she doesn’t realize is that she has been set for transport to Cleveland, and that Hank is trying to take her tag in order to avoid returning to the ocean. Dory doesn’t give it to him at first, explaining her situtation and her issues with short-term memory. However, the two come to an agreement that if Hank can help Dory find her parents, Dory will give up her tag to him.

Eugene Levy and Diane Keaton also join the cast as Dory’s parents. Dominic West and Idris Elba also provide their voice talents.

Finding Dory will hit theaters on June 17, 2016.
