Never saw Bravefart. Agree on Patton and The Caine Mutiny.
As much of the actual history is unknown, much of the film is speculative, but I did find that many of the details, such as Longhanks son being homosexual, were based on history.
BTW, speaking of Saving Private Ryan, am I the only one who found Tom Hanks a little mis-cast as the lead? I would love to see that movie with a young John Wayne as the lead. The tension in the movie was supposed to be the Captain's rough exterior contrasted to his inner self-doubts. The problem was Hanks doesn't have a rough exterior. There was no surprise when it was revealed his character was a teacher in civilian life, as Hanks looks like a teacher.
The beach storming scene in Ryan is great, but after that, the movie peters out. I thought the same thing about Full Metal Jacket. After Ermy's character is gone, the movie loses all momentum. Just my thoughts.
