Ellen DeGeneres’s affable and oblivious Dory stole your heart 13 years ago in Finding Nemo with her mantra “just keep swimming,” and quickly appeared, as a plush toy, on the bed of every child in America. Fans have been clamoring (get it?) for a sequel to the underwater adventure for years, and on June 17 we’re finally getting Finding Dory. The new trailer shows off the new characters (Ed O’Neill as a grumpy octopus, Idris Elba and Dominic West as lazy sea lions, and Diane Keaton and Eugene Levy as Dory’s parents), plus the old characters you love (Albert Brooks’s sapient clown fish, Hayden Rolence taking over for a now-adult Alexander Gould as Nemo, and that surfer turtle guy). It basically looks like the first movie, but with better animation and the memory of Blackfish lingering like so much flotsam. You can watch the first two trailers here, and listen to Sia’s song “Unforgettable” (get it?) here.
