It appears that the introduction of sound film coincides with the drafting of the Production Code. Did sound pose a threat more than imagery? Or was it the combination of sound and image that finally saw film evolving from a mere sideshow attraction to a genuine and ‘real’ mode of fiction consumption?
I remember a scene in Duck Soup where the Marx Brothers poke fun at the Production Code by showing a woman’s bedroom and then showing a woman’s shoes on the floor, a man’s shoes and horseshoes. Harpo is sleeping in the bed with a horse; the woman is in the twin bed next to them.
