"Acquire a peaceful spirit, and thousands around you will be saved." –St. Serafim of Sarov
There is actually a documentary about the life of Josyp Slipyj titled
Patriarch , directed by Oleksander Frolov (who also made an earlier documentary on Servant of God Andrey Sheptytsky). It was financed by parishioners from Ss. Volodymyr and Olha Ukrainian Catholic Church in Chicago. I believe one may obtain copies of the documentary from them.
Has anyone ever seen
Patriarch ? What did you think of it?
