Finding Dory trailer: Ellen DeGeneres returns for Finding Nemo sequel

Marlin and Dory show up in the new trailer alongside a host of new aquatic creations

It's been 13 years for us but only six months for the characters we first met in 2003's Finding Nemo, the majority of whom are returning for a new story that sees forgetful fish Dory (Ellen DeGeneres) search for her long-lost family.

Returning for the eventful ocean odyssey are friends Marlin (Albert Brooks), Nemo (now voiced by Hayden Rolence who replaces Alexander Gould) and Willem Dafoe's Gil. Even Mr Ray's (Bob Peterson) back for the ride.

Of course, this being a Disney/Pixar film, there'll be a fresh heap of new characters which include beluga whale Bailey, octopus Hank (voiced by Modern Family's Ty Burrell and Ed O'Neill, respectively) and unknown roles for Idris Elba and Dominic West.

The sequel will be directed by the original's Andrew Stanton (WALL•E) alongside Angus MacLane who graduates from Pixar short director to feature co-director.

Finding Dory will be released in the UK on 29 July and is the first of a roster of sequels due to come out in the coming years; these include Cars 3 (2017), Toy Story 4 (2018) and The Incredibles 2 (2019).

The studio's 2015 feature Inside/Out took home the Best Animated Feature award at this year's Oscars.
