It's Grits (1980)

With all the native wit, rib tickling humor and ability to see what makes the South the South found in the literary classics of Southern writers like Mark Twain, documentary filmmaker Stan Woodward helps us discover the common thread that connects the South’s people across all social, economic, political and racial boundaries – Grits! “Grits is us” - or, if we are to be grammatically correct, “Grits are us” - could easily be the title of this uproariously funny and at the same time insightful and poignant personal documentary.
