Just confirmed from someone in the know that this is Interlaced, not Progressive...really disappointing that such a great movie got short changed. For anyone interested, best bet might be to try to get hold of a US import version which is true 1080p and region free.
I have checked several of my Blu ray discs from EIV (Entertainment In Video) and they usually have an area on the bottom of the back cover with tech specs...where it will be highlighted if its 1080p. If however its blank or just says 'Anamorphic Widescreen 16x9' then its probably 1080i....which is sadly the case with 'The Reader'.
