Source for Perfect Blue's camera negative being destroyed According to the IMDB trivia on Satoshi Kon's Perfect Blue:


  The film's original 35 mm camera negative was accidentally destroyed. As a result, all copies are sourced from lower-quality prints. 


However I can't find any supporting source that this is true. Could someone find the source of this information (probably in Japanese)?
The closest source that exist on the internet is hearsay, according to an internet user on a forum post on the topic of the Bluray:


  
    What's the source on this? I've never heard of this before.
  
  
  The disc compressionist, privately to me.

All copies were sourced from telecine transfers (i.e. digital copies of the film), which is why you see certain artifacts and overall decreased quality.
