What happened next (only when you saw Red! (and White, spoiler!)
As many have noticed, Blue suggests that Julie is the true composer instead of her late husband. Olivier refuses to finish the piece without her, unless she reveals herself as the true artist.
Now, in the end of Red (major spoilers coming up now), all protagonists from these three movies are shown as the survivors of a major ferry accident. There, Julie is referred to as "the widow of the French composer."
Now, that tells us something, doesnt it? It suggests that she did not decide to come out as the true composer. Otherwise, for sure the news would have anounced her as the French composer Julie Vignon.
One thing bugged me about the film, and that is that losing all human connection and becoming fully disconnected from one's feelings, as Julie tried in Blue, never felt like any 'liberty' to me. On the contrary, scraping your fist against a wall to make sure you feel pain is not even close to liberty. Is her liberty not hidden in something else entirely? Do the film's themes not truly come into fruition after they have finished? As Red's Valentine will probably find only true fraternity with Auguste, the man she is meant to be with (as the younger equivalent of Joseph the judge), two wandering but inherently good souls, and White's Karol has only found true equality to Dominique after the jail time he got her as her punishment, Julie has only found true liberty by knowing she is appreciated for her genius by her great love Olivier but staying anonymous to the greater public. Any thoughts?
