I didn't see the recently revival of Fiddler with Al Molina (or Harvey Fierstein), so I can't attest to how well those were cast (I'd assume Molina was a better fit than Fierstein.) Other way around, actually. Molina wasn't very good as Tevye: strictly goyische, very cold, very dull. Not sure if that was Leveaux's direction, his being miscast, or a combination of both. Fierstein was wonderful--everything that Molina was not. His voice is what it is, but it didn't deter him from giving a moving, deeply felt performance.
Maybe we'll wait a few years before someone mounts another production, though. I don't really see any need.
"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."
