'Finding Dory' Trailer Swims Onto 'Ellen DeGeneres Show' with Nemo & Marlin!

It's been 13 years since Pixar's Finding Nemo was first released in theaters, and the film's highly awaited sequel, Finding Dory, is finally coming out this summer with Ellen DeGeneres reprising her role as the forgetful blue tang fish who is now searching for her family. In a new trailer that first premiered on DeGeneres' talk show, Dory teams up with Nemo and Marlin once more in a new quest!

The most recent full trailer for the film was released on DeGeneres' show on Wednesday morning, and it finally fills us in a little further on how the sequel will play out.

In the new clip, Dory sees how the stingrays begin their migration and she finds out they know where to go from instinct. Getting in touch with her own, Dory suddenly has flashbacks of her childhood and her parents (voiced by Diane Keaton and Eugene Levy), and decides to go on a quest across the ocean to search her roots, which leads to a new set of fun times, much like in the previous film.

"It was so much fun because I'd tell you a story and then you'd completely forget about it and then I'd get to tell it to you over and over again," says a childhood friend of Dory's in the trailer.

For this, Dory is accompanied by her two favorite clown fish, Marlin (Albert Brooks reprising his role) and Nemo (Hayden Rolence taking on the role previously voiced by Alexander Gould). Besides Keaton and Levy, other new additions to the voice cast include Michael Sheen, Idris Elba, Kaitlin Olson and Modern Family actors Ty Burell and Ed O'Neill.

Unlike the first film in the aquatic series, the "finding" in this case doesn't refer to anyone literally getting lost, but rather a metaphoric encounter, as a previous teaser had shown.

Finding Dory will be out in theaters on June 17.
