Yes, you've got to read "The Philosophy of Time Travel". See http://www.ruinedeye.com/cd/time1.htm if you have trouble reading it off the DVD.

Lena, have you read the short story Graham Greene's "The Destructors" refered to in DD? The text can be found at http://www.upol.cz/%7Eprager/e_texts/destructors.htm

What are your thought on the relationship between this and the movie?
