Those movie are Citizen kane of pre code films
An interesting pre-code film that often gets overlooked is “The Sin of Nora Moran” (1933), as it was made by poverty-row studio Majestic Pictures, and doesn’t tend to pop up on television. Very fascinating little oddity, which is woven with lots of flashbacks and even surreal imaginings, which were wildly original for the time. Even had a bit of mild profanity in it too.
