A Bridge Too Far: Good movie, reasonably historically accurate, and an amazing cast - a slew of Oscar winners and nominees on it (Gene Hackman, Elliot Gould, James Caan, Robert Redford, Michael Caine, Anthony Hopkins, Lawrence Olivier, Sean Connery, Maximillian Schell, Liv Ullman, Ryan O'Neill).
Das Boot: A bit slow at times, but is is as realistic a portrayal of submarine warfare in World War 2 that you will ever see.
Master and Commander: The Far Side of the World. Again, as realistic a portrayal of warfare in the Age of Sail as you will ever see.
We Were Soldiers: Any war movie that gave veterans flashbacks must be pretty realistic.
And one not often considered: Twelve O'Clock High. One of the first movies to show the psychological effects of warfare and PTSD, and still one of the best portrayals of it. Last I checked it was on Netflix; If you haven't seen it, you should.
And my nomination for the worst: Pearl Harbor. Michael Bay takes unrealism to a whole new extreme. If you want to watch an accurate portrayal of Pearl Harbor, watch Tora, Tora, Tora. Or From Here to Eternity. Or 1941. Or The Final Countdown. Or Finding Nemo. Anything but that god-awful movie.
!@#$ you. That's not a war movie. It's a science-fiction movie. And a travesty. So just !@#$ you.
Good post, DC Tom.
