Peter Weller (best known as RoboCop, but starred off-Broadway in THE WOODS and FRANK'S HOME) holds an earned PhD in art history/renaissance studies from UCLA and an MA in the same subject from Syracuse. David Duchovney did work towards a PhD in English Lit at Yale. Ashley Judd has an Master's in public policy from the JFK School at Harvard. I'm sure there are many others who have BAs, MAs, or even PhDs from respected universities in non-performance subjects. (I don't mean to cast dispersions on anyone's level of intelligence or degree, but an MFA in acting or voice is a performance degree, and not necessarily a marker of someone's intelligence/mental capacity)
"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."
