I don't think the London production was the great next step anyone involved had hoped for. The reviews were respectful but hardly raves, and it didn't transfer beyond its limited run at the Almeida.
I saw the show late in its run at the Atlantic and was impressed by the cast. The production itself was also visually striking (but a bit too abstract for the story). But the show overall wasn't very memorable. I'm guessing the pandemic zapped any hope of a further New York production and a lot of the Off-Broadway cast moved on to other projects.
"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
