This Australian cult film draws extremely dark humor from the story of Bubby, a man who has spent the first 35 years of his life locked in a disgusting basement by his abusive, controlling mother.
Having been taught that the outside air is poisonous and that leaving home is sinful, he only realizes the truth when his long-absent father returns to disrupt the already twisted family unit. A tragic confrontation follows, forcing Bubby into the real world.
Knowing nothing about life, and undoubtedly suffering from mental disturbance, he stumbles about the city, speaking in a rambling monologue made up mainly of overheard phrases. His behavior is interpreted in different ways by the people he encounters: some think him insane, while others equate his strange speech and erratic behavior with brilliance.
The edgy lead performance by Nicholas Hope is key to the film's success, managing to make Bubby a figure that is both sympathetic and at times quite frightening.
