Ellen DeGeneres’ scatty blue tang Dory makes an endearingly funny heroine of this highly enjoyable sequel to Pixar’s Oscar-winning 2003 animated movie, Finding Nemo.

She’s on a quest to find her missing parents, a venture made all the more daunting, of course, by her short-term memory loss, but one which she tackles with intuitive daring and bumbling pluck.

Headstrong young clownfish Nemo (Hayden Rolence) and his neurotic dad (Albert Brooks), Dory’s former companions, help her on her way. However, when she ends up stranded alone inside a California marine park, it is Hank (Ed O’Neill), a shape-shifting octopus (she calls him a ‘septopus’ as he is missing a limb), who comes to her aid .

Animation-wise, this movie can’t surpass the original, but it does introduce us to some engaging new characters – including a hopelessly myopic whale shark (Kaitlin Olson) and a pair of cockney sea lions amusingly voiced by Idris Elba and Dominic West – and the gags are consistently good.
