Click here for an interview with Sarah Polley:
"I think I was always aware from the beginning that I wanted to include the construction of the film in the film, because that was an important part of what we were talking about. This idea of wanting to tell stories and how we are telling the stories. I thought to leave my own process of making this story out of it would have been dishonest in some ways, so I think in its inception it was really important to include that and for that to take the form of re-creations and then showing the mechanics and those re-creations."
