As I understand it the Patriot isn’t that accurate. I think Saving Private Ryan is regarded as being pretty realistic.
I teach HS history. First question I would ask is what context are the movies being shown in? Is the teacher just popping them in and grading in the back? That’s a lot of lost class-time.
I would only show the opening of Saving Private Ryan (D-Day Landings) which is about 25 min. The rest of the move (another 2 1/2 hours) is not necessary.
Patriot is a joke, don’t bother.
Glory is a good one, I would show that in its entirety.
I never saw Uprising, and only vaguely remember We Were Soldiers.
The Story is entirely fiction, but the costumes, and weapons, and their use is dead on. The person adviser in charge of it is a member of the Simon Gurty (Sp?) reenactment group. He spent hours with Mel teaching the proper way to wear and use the equipment.
