Frankly, kind of surprised that the play is being revived again
I'm guessing this was the case of a star wanting to do a certain role. Kline is notoriously reluctant to commit to stage projects, and he's been bankable in the past (his Cyrano recouped despite playing a very brief engagement); the producers probably thought there was money to be made. But this does seem like a case of a play nobody was particularly dying to see, in a theater way too large for the play to be done effectively. I haven't seen it, and now I probably won't plan to.
The best production of this play I've ever seen was at Two River Theater in New Jersey, in 2013, with Michael Cumpsty as Garry. It was done in a 300-seat theater and the jokes really landed, and the production was gorgeously appointed. The supporting cast was really quite strong too: Kaitlin Hopkins, Camille Saviola, Veanne Cox, and--in a stroke of truly brilliant offbeat casting, the cabaret/performance artist Cole Escola as Roland Maule. I wish that production could have had more of a life, but it's probably better it was left as it was.
"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."
