The new film will be released in November 2015 and will be set  year after the events of the first film, in which Nemo’s father Marlin, voiced by Albert Brooks, and Dory, voiced by Ellen Degeneres, went on the search for the missing little fish.

“I’m not mad it took this long,” Degeneres said of the news that a sequel with her character as the lead is in the works. “I know people at Pixar were busy creating Toy Story 16. But the time they took was worth it.

“The script is fantastic. And it has everything I loved about the first one: It’s got a lot of heart, it’s really funny and the best part is – it’s got alot more Dory.”

The new film will be directed by Andrew Stanton, the Pixar genius behind not just the original Nemo, but also sci-fi stunner Wall-E.

Finding Nemo was released on 2003 and won the Oscar for Best Animated Feature as well as scoring more than £600m at the global box office.
