Since its 2013 release, the documentary "Blackfish" has inspired the public to reexamine SeaWorld's treatment of its captive orcas, and has provoked criticism from everything about orca life spans to the way the park separates mother orcas from their babies. With plummeting park attendance, SeaWorld has struggled to recover its public image since "Blackfish," and just this year SeaWorld announced its plan to end its orca breeding program, effectively making its current generation of orcas its last.
In fact, it was this documentary that inspired the anti-captivity message in "Finding Dory." According to the New York Times, filmmakers pushed back the movie's release date in order to rewrite the script in light of the groundbreaking documentary.
If the shots in this new trailer, along with DeGeneres' previous hints, are any indication, it appears this will be a thought-provoking and inspirational movie for children and adults alike.
