You’d be forgiven for thinking that Finding Nemo didn’t really need a sequel. It was a completely charming, yet contained adventure, wrapped up pretty neatly. But, it was a very, very successful Pixar movie and, these days, that means sequel.

As you can see in the trailer, Finding Dory finds Dory still very much being Dory, but with one very, small change: she’s slowly starting to remember things. It’s not all coming flooding back at once, but as Dory dreams, she remembers her family and sets off, with the help of Marlin and Nemo, to find them.

Though another sequel doesn’t seem like the most exciting thing Pixar could be doing, especially when Inside Out was one of the best films of the year, but if director Andrew Stanton is able to bring even a little bit of magic from the original back for Finding Dory, it may be worthwhile. Even just watching this short amount of footage, it’s hard to deny the thrill (and the beauty) of being back in this underwater world.

Original Finding Nemo stars Ellen DeGeneres and Albert Brooks are both returning for the sequel along with newcomers Ed O’Neill, Kaitlin Olson and Ty Burrell with Eugene Levy and Diane Keaton starring as Dory’s long lost parents. Finding Dory opens in theaters on June 17, 2016.
