When the 100-year-old man in question — the simple-minded Allan (Robert Gustafsson) — gets revenge on the fox that killed his cat by blowing the fox up, he's exiled to a nursing home. Allan's subsequent escape leads to a cross-country chase involving the police, a motorcycle gang, and an elephant while Allan flashes back to key moments from his century. Comparisons to Forrest Gump are inevitable, but unlike that film's unpleasantly conservative morality, The 100-Year-Old Man Who Climbed Out the Window and Disappeared is gleefully amoral, while also ruminating on how families are formed.
