While much has been written about Keaton’s loss of control working for MGM,
What No Beer? (1932), Buster's final MGM picture, contains a pure, elaborately staged “Keatonesque” moment, when Buster struggles with a truck load of beer barrels on a steep hill, recalling the avalanche scenes from his silent feature
Seven Chances (1925).
