The Los Angeles Times revealed in an interview with the actor that one condition of his contract was "that he be allowed to mold the part in his image."
A nice way of saying that he wasn't going to even bother trying to learn the part as written. Not that it really matters with this POS.
"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."
