I watched the film yesterday I and think it's a great companion to "The Three of Life", though less ambitious and less innovative, because most techniques and narration forms were already in the previous film and even on "The New World". But I loved the use of extreme wide-angle lenses (12mm Master Prime?), which works better in the Super 35mm 2.40:1 ratio of this picture than in the standard 1.85:1 used for "The Tree of Life".
I saw it digitally projected and I was able to tell the night scenes in Paris, and Javier Bardem's visits to the hospital and prison were where they used digital adquisition. But I could spot it because I already knew some bits of the picture had been shot digitally and was looking for them (the Red MX footage seemed a bit softer and cleaner in comparison). Don't know why they switched to HD for these scenes though, as it seems that Lubezki's constant penchant to use the whole dynamic range of this negatives isn't the ideal scenario for the pre-Alexa HD sensors (this picture was mostly shot in 2010).
Anyone with an interest in cinematography shouldn't miss it.
