A brand new trailer for 'Finding Dory' has been released, and this time we get a glimpse of her long forgotten past. It's actually the third trailer from the movie, and we really don't think we're going to last much longer with all this excitement.

Finding DoryWill Dory finally find her folks in Finding Dory?

It's kind of a sad story; as it happens, Dory has always struggled with short-term memory loss, resulting in her losing her family at a very young age. A young Dory can be heard calling out into the gloom of the ocean, to the dismay of two passing fish voiced by Kate McKinnon and Bill Hader.

As the years have progressed, she can barely remember what she's looking for anymore, but she's always got a niggling feeling that she's forgotten something important. When she eventually remembers that she's been separated from her family for most of her life, she sets out on an adventure to find them again - to the deep concern of Marlin and Nemo, who know only too well the dangers of the ocean and what a liability Dory is to herself. And as she gets whisked away to a marine life institute, who knows who she's going to meet?

Watch the trailer for 'Finding Dory' here:


Along with the return of Dory (Ellen Degeneres), Marlin (Albert Brooks) and Nemo (Hayden Rolence), we meet a whole host of new characters in this trailer. There's Hank the rather grumpy but gentle octopus (Ed O'Neill), Becky the scatty loon (Torbin Bullock), Destiny the friendly whale-shark (Kaitlin Olson), and chilled out sea lions Fluke and Rudder (Idris Elba and Dominic West).
