No, this is something I would object to with my stuff. With a different but 
sufficiently strong copyleft license? I would probably go for that. With 
essentially a BY licensed movie? I doubt it. If the BY applies to the movie 
as a whole. My stuff would end up BY and then all rights reserved with 
someone else holding the rights. No thanks.

This really is a hairy issue, isn't it.
