an actor and met them and didn't feel like they were there for the ride of it, it wouldn't be in the film.  Very much they needed people who were prepared, who wanted it and who were open souls, and people whose work they liked or maybe they'd worked with some of us before.  [They wanted] people who were open to possibilities, open to others and open to the journey that we were going to be making, which was very much into territory that filmmakers haven't really gone into before.  I think that spirit of inquiry and adventure and the idea that it was a voyage, if the actors weren't prepared to embrace that idea, not just embrace it but actually be eager to be part of that, then I don't think Tom or Lana or Andy would have [chosen them].  None of the actors would be there and that's why we've got an incredibly harmonious and joyous group of people.  We're being cast because...I mean, there are great names in the film, but it's not just let's get all these names, and let's do all this, and let's get all this money, and let's package this up.  None of those people know each other or think alike or get on at all.  This is a group that's come together over time who have a similar sense of wonder and delight in exploring the world and trying new forms and that's why it's been such a great experience for all
