Humor in Film

 Whether successful or not, Duck Soup, The Great Dictator, and Dr. Strangelove are comedies with tremendous political and social implications, especially concerning the times in which they were produced. Some Like It Hot does the same thing with gender and sexual politics, Blazing Saddles with race among other issues. How do they compare to the comedies of today that are attempting to put forth similar messages. What may have contributed to any changes or consistencies: culturally, politically, socially, economically?
