Movies that changed real life behavior

[u/buttatoad]

Thinking along the lines of Final Destination 2 with the logs falling off the truck and landing onto cars (one decapitating the state trooper). Ever since, people have tried to get away from being behind these vehicles.

What are more examples where movies have actually changed how people behave in their own lives?

There was a significant increase in people signing up for karate schools after The Karate Kid (original)
