The chipper--if chronically forgetful--blue tang of “Finding Nemo” swims into the spotlight in Pixar Studios’ smash subsea sequel. When Dory (voiced by Ellen DeGeneres) touches on a fleeting memory of the family she got separated from, her adoptive clownfish clan Marlin (Albert Brooks) and Nemo (Hayden Rolence) follow on a hopeful, exciting and touching underwater odyssey.
