FBI documents from 1947 show that government officials once believed the Christmas movie classic “It’s a Wonderful Life” was Communist propaganda. About the FBI memo titled “COMMUNIST INFILTRATION OF THE MOTION PICTURE INDUSTRY,” Blogger Will Chen writes,
I love It’s a Wonderful Life because it teaches us that family, friendship, and virtue are the true definitions of wealth.
In 1947, however, the FBI considered this anti-consumerist message as subversive Communist propaganda (read original FBI memo).
According to Professor John Noakes of Franklin and Marshall College, the FBI thought Life smeared American values such as wealth and free enterprise while glorifying anti-American values such as the triumph of the common man.
