The screwball comedy is a principally American genre of comedy film that became popular during the Great Depression, originating in the early 1930s and thriving until the early 1940s. Many secondary characteristics of this genre are similar to the film noir, but it distinguishes itself for being characterized by a female that dominates the relationship with the male central character, whose masculinity is challenged. The two engage in a humorous battle of the sexes, which was a new theme for Hollywood and audiences at the time. Other elements are fast-paced repartee, farcical situations, escapist themes, and plot lines involving courtship and marriage. Screwball comedies often depict social classes in conflict, as in It Happened One Night (1934) and My Man Godfrey (1936). Some comic plays are also described as screwball comedies.
