There is a film about him which I saw on Netflix, the title of which I can’t remember. But I believe his name is part of the title. He was indirectly involved with those who carried out the unsuccessful August, 1944 attempt on Hitler’s life. The gal who plays his fiance is a real classic Germanic beauty. Va-va-va-voom! Bonhoffer was not a conservative as we think of conservatives these days. He had not sold out on Christian biblical beliefs but he appeared to have some ecumenical as opposed to separatist beliefs.
The film was made for public television and thus played up some doubtful liberal bonafides for the sake of its liberal audience.
