We've already had two trailers for Finding Dory so far but this latest one is by far the most revealing yet. 

While we knew that plot would revolve around Marlon and Nemo trying to rescue their friend Dory (the title kind of gave it away), the new trailer gives us some specifics about what that will entail. The trailer also gives us a brief glimpse into Dory's past and how she became separated from her family. 

Ellen DeGeneres, Albert Brooks and Hayden Rolence are all reprising their roles from the original and are joined for the sequel by Idris Elba, Kate McKinnon, Bill Hader, Dominic West, Diane Keaton, Ed O'Neill, Kaitlin Olson, Ty Burrell and Eugene Levy.
