Dear @Alojzije Kardinal Stepinac , there are several films available about Mindszenty. Unfortunately only in Hungarian. Pls contact the Mindszenty Foundation, they must be aware about any documentary with a subtitle:
Kezdőlap | Mindszenty Alapítvány (mindszentyalapitvany.hu)

Pls note there is an ecellent Polish film about Cardinal Stefan Wyszynski. Amazon sells dvd with English subtitles
