The host shared the official first look at the eagerly awaited sequel – which is a follow up to 2003’s hit film Finding Nemo.

“I think that fish should be in the ocean. It’s what this whole sequel is about,” Ellen has said of the film’s plot.

“It’s about rehabilitation and putting them back in the ocean,” she added.

“We have to protect our oceans. Hopefully that discussion starts with this film, because we really need to protect that environment.”

Finding Dory will focus more time on the fish voiced by the popular TV personality – who recently opened up about coming out as gay – after her character sets off to find her family.

The first trailer – which DeGeneres premièred on her YouTube channel – shows Dory finally regain some of her allusive memory, which leads her on an epic journey of self-discovery.

“The movie will be mostly set at the California Marine Biology Institute, a huge complex of sea life rehabilitation and aquarium, where Dory was born and raised,” said Pixar president Jim Morris.

“We will get to meet new characters, like an octopus, sea lions, a beluga whale, among others.”

It will also bring back characters voiced by Albert Brooks and Willem Dafoe – as well as bringing Diane Keaton and Idris Elba into the fold.

Finding Dory is set for release in the US on June 17 and UK on July 29 2016.
