Another great interview!  Thanks domino.

One thing that comes back in every interview is their desire to for truth in this film...the training, the location, filming chronologically.  I am really fascinated by the idea that the actors improvised between scenes to help develop the characters and their relationship.  Presumably it was all caught on film....it would be amazing to be able to see some of it in the future!  Although obviously I'm desperate to see the film first!!
