America's Grandpa

Will Geer was a political activist and agitator, blacklisted during the McCarthy era, as well as the reassuring “America’s grandpa" in the TV series The Waltons; a militant socialist, a staunch defender of gay rights, and the forefather of one of the nation’s most beloved families, whose progenitors are played by two celebrated residents of Sodom (Geer himself) and Gomorrah (Ellen Corby). But Will Geer is also an actor who has collaborated with great directors such as Mann, Preminger and Frankenheimer and who, through films, has challenged, reflected and subverted modern American history, perverting the rules of the establishment that had gagged him, in order to corrode it from the inside, unsettling it with the face of a man who was "born to be old", an adorable little old man with a sly look of a man who has built a new world.

There was a trailer...but, it has since disappeared.
