12 Monkeys
This Bruce Willis action film is based on the famous French art film, La Jetee, a film composed only of still photographs. Time travel can be powerful, but it’s also bittersweet. Both time travel movies look at how to alter time, especially to avoid epic tragedy. Willis is trying to prevent a major health epidemic with dire consequences. All his zipping through time has allowed him to witness his desperate future. But if you see violence happen in advance, are you still able to prevent it? Especially if you’re the victim?
Time travel stories can be fun, but they just don’t make sense scientifically. These are the most scientifically inaccurate movies ever.
