“Titanic” was not *too* bad. ‘Apollo 13’ got most of the facts right from what I know, not sure as to the personalities.
I always got a kick our of ‘300’ because I think that movie is *EXACTLY* the way the Spartans would have liked to view themselves; obviously it wasn’t ‘accurate’, but I bet to a man they would have enjoyed it.
In the fiction sense, the one I would most like to see would be a dead-on version of ‘Starship Troopers’; *NOT* the POS of that name that was made, but if they’d just follow Heinlein’s book it would be an awesome movie.
Ron Howard’s Apollo 13 turned the contracting corporations into villians which NASA staff argued against repeatedly while the film was in development.
