How did the loveable but forgetful fish Dory lose her memory? All appears to be explained in the new Finding Dory film
The scatterbrained blue tang is getting her own spin-off and in the latest trailer we get to see a younger Dory at the moment she loses her parents.
"Hi, I've lost my family," she says. "Where did you see them last?" a friendly fish asks, to which a worried Dory replies, "...I forgot."
Now on a quest to find her family, Dory is thwarted when she's captured and taken to a marine life institute.
She joined by everyone's favourite clownfish Nemo and dad Marlin as they try to help Dory discover her past, reconnect with her parents and find out how she learnt to speak whale.
Ellen DeGeneres returns to give life to Dory, while Albert Brooks reprises his role as Marlin and Hayden Rolence takes over as a grown-up Nemo.
Plenty of brilliant new characters get introduced too, like lazy sea lions Rudder and Fluke, voiced by Dominic West and Idris Elba (imagine how fun that voice recording session was).
Diane Keaton and Eugene Levy voice Jenny and Charlie, Dory's parents, while Modern Family's Ed O'Neill stars as Hank, an irascible seven-armed octopus, and Ty Burrell as Bailey, a beluga whale.
Finding Dory swims into cinemas on July 29.
