Amnesia is a concern for the heroes of two blockbuster sequels – the Pixar animation Finding Dory and the espionage thriller Jason Bourne. The condition extends to the film-makers, who have forgotten much of what made the original movies so appealing. In fairness, the 2003 Finding Nemo lacked the emotional complexity of top-drawer Pixar. But its story of an anxious clownfish combing the ocean for his lost son served as a neat rebuke to worrywart parents, and it featured one enduring character: the Pacific blue tang Dory. Her short-term memory loss left her in a state of carefree enchantment perfectly expressed by Ellen DeGeneres, whose voice calls to mind a rubber ball thrilled afresh by each new bounce.
Now Dory has a movie of her own, in which she goes in search of the parents from whom she was estranged as an infant. Many of the previous picture’s fish chip in to help, but the script’s argument for inclusivity and diversity is made most persuasively by Dory’s new allies. Hank is a tomato-red octopus who can’t bear to be touched, while Becky, a frizz-haired loon, and Gerald, a bullied sea lion, have learning difficulties that leave them vulnerable to mockery by their fellow creatures. Heroism originates here with the apparently disadvantaged, whose differences ultimately prove to be no sort of disadvantage at all.
