As great as that idea might sound in our heads, keep in mind that aside from a few TV appearances here and there back in his acting days, Joe Mantello has never been a film actor. And I'm not necessarily sure that the wonderful kinetic spark that made his performance so memorable would translate to a different medium. What works brilliantly on stage doesn't always come off so well on film. And besides, his directing schedule would probably preclude him from a film shoot. (Here's hoping he does another play, though!)
It wouldn't surprise me if someone like Parsons ended up playing Tommy in the film, although I can't imagine Pace getting the role of Bruce over a more established/recognizable name actor who might want it. And next to named like Bradley Cooper and Julia Roberts, Hickey and Barkin don't stand a chance.
"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."
