An entrepreneur with a world-class ego has to rebuild his empire and his family relationships from scratch in this comedy. Robert Axle (Kevin Spacey) built a multi-million-dollar business out of selling household gadgets through television infomercials, and managed to alienate nearly everyone around him when fame and wealth turned him into an arrogant loudmouth. When one of Axle's products turns out to be dangerous and causes several thousand customers to lose a finger, he loses his fortune and spends eight years in prison for gross negligence. Back on the street, Axle is broke but determined to find a way back to the top, though he's just a bit more humble than he used to be and wants to win back the love of his daughter, Claire (Camilla Belle), whom he neglected as a child, and his ex-wife (Virginia Madsen). Things go badly for Axle on his first day working at a big-box discount store, and he's left with little alternative than to ask Claire to let him stay with her; she and her roommate, Fibbi (Heather Graham), aren't so sure this is a good idea, but they grudgingly agree and end up helping Axle in his bid to redeem himself. Father of Invention also stars Johnny Knoxville, Craig Robinson, and Michael Rosenbaum.
