Motion Picture Production Code
Morocco is an early Pre-Code romantic drama starring Marlene Dietrich and Gary Cooper, two eventual stars that came to epitomize Hollywood.
Screwball comedies came around in the 1930s, due to the Motion Picture Production Code. The genre is still popular today, and some filmmakers try to recreate the themes and techniques in modern films. By 1934, the production code was being enforced in the motion picture industry.
