What movie in the past wouldn't get the greenlight for production today because it would be considered to offensive?

Yes most definitely

Anything from the 80s about an underdog boy into a girl, and thank god for that--they were all about stalkers and rapists

Not a movie but A series Shameless

Shallow Hal. Think it was deemed borderline offensive when it came out.

sanford and son tv show

Blazing Saddles

I would say the original Exorcist

Tom cruise in this was hysterical 😭

American Pie, Revenge of the Nerds.

Young Frankenstein
Porkys
