Are you tired of Hollywood movies and all their socio-political rants? They certainly do make a good many of them:
•Nuclear power................They're against it ("The China Syndrome").
•Antisemitism...................They're against it("Gentleman's Agreement").
•Alcoholism......................They're against it ("Lost Weekend").
•Racial segregation................They're against it, but in 1915 they were for it ("Birth of a Nation").
One glance at this 1939 article and you'll be able to blame it all on the poet Archibald McLeish (pictured above: 1892 – 1982) who clearly advocated for political posturing in American movies.
No doubt, McLeish must have been very happy when Warner Brothers released Confessions of a Nazi Spy in April of 1939; it was the first Hollywood film to take a swipe at the Nazi war machine.
