"The year is 1717. Wealthy landowner Stede Bonnet has a midlife crisis and decides to blow up his cushy life to become a pirate. It does not go well. Based on a true story," the synopsis for the show reads.
Waititi stars as history's most feared pirate Blackbeard, and you may not even recognise him in the trailer.
The Oscar-winning filmmaker commits to the role with voluminous facial hair. Although, we don't catch more than a subtle glimpse at him in the teaser released today.
The clip from the new show introduces Darby's hilarious role and a dash of the classic Kiwi humour we are used to seeing from him and Waititi's projects.
But lucky for Waititi fans he debuted his pirate transformation on his Instagram account.
"Sheeit it's f**** Blackbeard bro! The seven seas will never be the same again..." he teased, alongside stills from the show featuring him in full costume.
2022 is set to be a big year for Waititi, who reprises his directing duties and his role in Marvel's Thor franchise. Thor: Love and Thunder is slated for release in July 2022.
Watch the teaser trailer for Our Flag Means Death above.
