I thought it was a great addition to our reading and we all learned a little something from it. I really liked the role of his conversion and how his strong belief in the Bible affected him and was represented in the movie (something that would never be shown in a film today, at least not positively). The first hour of the movie is building his character and showing who he is and where he came from with the second half delving into the war and related events. It doesn't have the speed or graphics of modern films (it was made in 1941 I believe) but in my opinion, is all the better for it!!!
Any more WWI related resources you might be aware of that we could look into?
