Swinton plays a pioneering livestock expert who wants Okja to be used as a food produce, while Mija's rescue mission - which takes her to Manhattan - is aided by animal-rights activist Jay (Paul Dano).
Okja is the good cry you didn't know you needed today.
The newly-released trailer for the Netflix original film, written by Bong and Jon Ronson, sets up the main conflict - all set to the tune of the Mamas and the Papas' "Dedicated to the One I Love".
The full trailer for Okja has arrived, finally lifting the viral veil that previously covered its crucial details, notably the titular creature, which is revealed to be - as previously hinted - a giant grey pig-type creature resembling an oversized land-walking manatee.
The trailer doesn't address our biggest question: why would someone engineer an animal meant for food that also happens to be not only adorable (seriously, he somehow looks like the offspring Eeyore, Piglet and Winnie the Pooh) but a ideal companion for humans?
Giancarlo Esposito, Jake Gyllenhaal and An Seo Hyun. However, we should get a great idea of the critical consensus once it premieres at the Cannes Film Festival on May 19.

This composite image provided by Netflix shows scenes from the main trailer of "Okja", an upcoming movie by South Korean director Bong Joon-ho. Her daunting journey to bring her friend home becomes complicated as she crosses paths with groups of capitalists, demonstrators and consumers, each battling to control the fate of Okja.
