Stranger Things's David Harbour and Fantastic Beasts star Alison Sudol have been announced as ambassadors for Greenpeace, and will voyage to the Antarctic waters to safeguard various species, including whales and penguins, for the charity's Protect the Antarctic campaign.

Harbour commented 'Well, Greenpeace says the Weddell Sea and its surroundings are home to a precious ecosystem, vital to sustaining our future. And that there's penguins there. And that I’ll get to waddle around with them, discuss their parenting techniques with them and yes, yes, dance with them. And that they’ll film it. And that if maybe I get enough support from everybody, they’ll gimme that video, so I can rent it out to you (be kind, rewind please)'.
