This film was made by a small production company and most of the actors are unfamiliar. However, in spite of this, the film is a well-made drama about an amazing man of faith, Dietrich Bonhoeffer. He was a German Lutheran minister who managed to make a nuisance of himself--and as a result he spent the last part of WWII in prison awaiting execution.
Overall, this is a very good film and was a treat as a historical and religious film--though its Biblical message is not even close to heavy-handed or preachy (so anyone can enjoy it and its message). The acting, sets and direction were also quite good. My only reservation concerns the tempo of the film--it is very, very slow-paced and low-key. Some might be put off by this, but if you can get through this you'll likely enjoy learning about this interesting man. Not great, but very good--especially with such a small budget.
By the way, I did a tiny bit of research about this man and was surprised to see that the actor playing him actually looked very, very much like Bonhoeffer.
