Manhattan Theatre Club recently added this play to their Off Broadway season as well, beginning in October. They have been added as a co-producer. This is perhaps not surprising since Mandy Greenfield, WTF's current artistic director, was formerly MTC's artistic producers; in recent years a number of shows have gone from WTF to MTC.
It's playing a 2-week engagement at Williamstown in August. There have been other plays that have premiered before being produced at Williamstown.
I don't know who has been cast in the Geffen production or whether all three productions will have the same cast. I saw the casting breakdown, and it's a two-character play--a Jewish woman and an African-American man, both early 20s to play college freshmen.
Actually at MTC
"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."
