It's official, the folks at Disney have finally settled on a name for their Finding Nemo sequel and, funnily enough, it's Finding Dory. The first official teaser image and plot line for the film have just been released, and pretty much half the internet thought it was a belated April Fool.

Anyway, the brand new Disney Pixar film focuses on Dory, and explains how she came to be swimming on her own in the deep blue sea. Veteran director Andrew Stanton, who will return for the sequel, says the film takes place about a year after Finding Nemo, and sees our favourite clown fish, his daddy Marlin, and the Tank Gang all return. There'll be a whole host of new characters too, including some who will turn out to have a rather important role in Dory's life.

"I have waited for this day for a long, long, long, long, long, long time," said Ellen DeGeneres, who will reprise her role. "I’m not mad it took this long. I know the 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 a lot more Dory."

Finding Dory is due to hit cinemas on November 25th 2015. Until then we guess we'll have to just keep swimming...
