John Carter isn’t about geology at all, so it’s really not a “Bad Geology Movie.” However, it’s worth inclusion here because it was filmed in a place that has some really darn awesome geology.
Those aren’t (all) matte paintings folks. That stuff is real! Features might have been added, but the settings are real.

This is the area where I studied geology, all those years ago. Watching John Carter took me home. If you want to see some spectacular geology while watching a movie, you should check out this movie!
