The new movie reportedly takes place six months after the events in Finding Nemo, with Dory happily settled and living with the marine community in the same reef as Marlin and his son. She still has issues with her memory, and when she attends one of Nemo's class trips to watch manta rays migrate home, she starts to have serious feelings of homesickness and wants to learn where her family are now.
According to Morris, that will be on the California coastline as "the movie will be mostly set at the California Marine Biology Institute, a huge complex of sea-life rehabilitation and aquarium, where Dory was born and raised. We will get to meet new characters, like an octopus, sea lions, a beluga whale, among others."
Collider also brings word that the setting has been shifted in the last couple of years, as the original locale was a SeaWorld type facility, somewhere Pixar is likely to want to avoid given the Blackfish (2013) backlash. Still, animated features change these things up all the time, and Pixar in particular is willing to scrap ideas midway through production. With Albert Brooks (Drive), Ty Burrell (Dawn Of The Dead), Idris Elba (Prometheus), Dominic West (300) and Vicki Lewis (Finding Nemo) in the cast, Finding Dory will float our way on 29 July 2016.
