===============================================================
Do note:
Zatoichi and the Fugitives has been trimmed by 4 seconds due to animal cruelty (thanks given to Dr Amicus for this discovery)
Andrei Rublev + War and Peace were both canceled after being announced, due to animal cruelty footage, which Criterion didn't feel like removing, I guess.
