Yesterday I watched this movie for the 2nd time and I finally understand it. Well, I think I understand it, I have a theory and the pieces start to fit together. It’s one of the most brilliant movies I’ve ever seen. At the end one just sits there and thinks “What the heck was this movie about?!” It leaves you thinking for days! I think Diane and Camilla were together, then Camilla run off with the director guy, Diane collapsed and hired a hitman to kill her. When he did, Diane went totally crazy and finally killed herself. The first part of the movie was a dream of hers, or possibly a flashback just before she died, a last glimpse at her life, but in an idealized way. Same characters, different roles. The blue key is the sign that Camilla has been killed. In her dream it opens a blue box where all her shame and demons are closed ( old couple, man behind Twinkies, etc…) The theater part tells us that what we think is real isn’t really so, it’s only an illusion (of Diane’s ) Then in the end the lady with blue hair says “Silencio” = death. The only thing that could shut Diane’s demons up and bring her peace. I’m curious, what are your interpretations?
