Steve Martin incorrectly interpreted Sullivan's Travels
Saw STs recently and notice what made people happy was laughter. They did not wish to feel miserable or see the condition of the wretched onscreen. They wanted to be happy.
Steve Martin's character produced violent action films. He interpreted the modern action film as providing the same release as comedy provided to Depression-era audiences.
I would say that the feelings generated by humor and violence are not the same. He could have made feel good movies where people do unselfish or humorous acts or both. He elected to focus on the violence and raciness.
