I saw Metcalf in London, and have watched the filmed version through the Digital Theatre website. It's a shattering performance, and the film captures the enormity of Metcalf's accomplishment. It's absolutely worth renting. In addition, the entire London production was terrific, with great performances from David Suchet, Trevor White, and Kyle Stoller (whom I wish was playing Edmund on Broadway over JGJ). In just about every way I prefer it to the current production.
"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."
