This was an interesting experience. Since I had already read Mark Harris' excellent book of the same name, a lot of these stories were old news to me and that really held me back in the early chapters. I mean it was cool getting to see some of the footage that I'd only read about, but nothing new was really brought to the table. There wasn't anything that really justified this being a film rather than a book. But then there's that final third. In its final hour, this doc really becomes cinema. As fascinating as I found the book, it didn't move me. The final segment of this film moved me greatly. Five Came Back will go down as one of the finest documentaries about cinema ever.
