Deliberate mistake: The documents to which the Imperial Seal was stamped at both the coronations in Peking (1908) and 'puppet' coronation in Manchuria (1934) carry the same dates. They also show the same 'coronation names' when it is known that Puyi was coronated as 'Xuantong' in Peking and 'Kangde' in Manchuria. This will only be apparent if one can read Chinese. It might have been a deliberate mistake by Bernardo Bertolucci who decided to use spare, unused props from the first coronation scene for the second one. The timecodes submitted correspond to the PAL version of the DVD. (00:14:45 - 01:47:40)
Continuity mistake: When the new bride is kissing Pu Yi, she leaves some lip marks all over his face, but these marks change from shot to shot.
