What Movies Best Mix Fiction with History?
I love stories that tie in fictional, even fantastical, events, with big historic events.
Maybe the best example is X-Men: First Class, in which we find out it was really the X-Men who saved us in the Cuban Missile Crisis. Incidentally, the next film says that it was Magneto who curved the "magic bullet," and X-Men Origins: Wolverine, which ties into the Three Mile Island incident.
Another favorite is the Rocketeer, which (spoiler alert) ends with the villain crashing into the Hollywoodland sign, destroying the "Land" part.
I believe the movie Chinatown is about the real events surrounding L.A. drinking water in the '40s, and a third film in that series would have dealt with the construction of the L.A. freeway (which was covered, instead, in Who Framed Roger Rabbit).
What are some other good examples?
