btdt - thanks. I'm also looking into other angles of it - wp is just one method of research. I'm going to learn as much as I can for a while, then try to figure out how exactly to make best use of the film's time limit.
Anbuend, just wanted to let you know that I've now read Getting The Truth Out. It's very well-written and moving. Also sent you an email, although not had a response yet, so am mentioning it here in case it didn't send properly...?
