WATCH: First full trailer for "Finding Dory"

The sequel to the 203 hit is finally here

Its been 13 long years Dory helped Marlin to find his missing son, but now the tables have turned.

Premiered on The Ellen Show today, the much-loved talk-show host has returned to voice the eternally short-term memory losing fish who suddenly recalls that she has a family somewhere out there in the big blue ocean, and she sets out to the find them.

Directed by Andrew Stanton, who also directed the original, Finding Dory has some big gills to fill, considering the original made over $930 million at the box office and went on to win Best Animated Feature at the Oscars.

On top of the returning voice cast from the original, new recruits include Diane Keaton, Eugene Levy, Ty Burrell, Ed O'Neill, Idris Elba and Martin Sheen.

The movie will "just keep swimming" into Irish cinemas on July 29th this year.
