Great podcast. The part about the camera not working killed me. Was hoping for more stories about one-on-one's with Ridley but he's a busy guy with a schedule to keep and all that.
Shame I don't really know much about Moebius. The chap you interviewed said he could pick up a lot on the smaller, more subtle references or nods, but perhaps not a more casual viewer, especially someone who only knows the artist by name.
He mentioned putting one epic visual thing in the film, somewhere, and hopes it makes it into the theatrical cut. I wonder what that was...
