"Never give a inch!" is the Stamper family motto, and this is a film full of (stubbornly) manly men with (desperately) gritted teeth.
Obviously, no movie could ever approach the scope of Kesey's tome, but in atmosphere and characterization, this 1970 film is pretty spot-on. It's a time capsule of a way of life and image of masculinity that were already dying in the 1970s and have faded to distant memories in the 2010s.
Sometimes A Great Notion plays nightly at 6:30 and 8:45 at the Grand Illusion through Thursday night.
