Even first rate actors like Kevin Spacey cannot save a film just on their name alone, they need a better script to work with. In this case Kevin Spacey plays a successful multi-millionaire inventor named Robert Axle who ends up serving a 10 year prison term for inventing and releasing prematurely an exercise machine that severs fingers from a number of purchasers. Robert Axle invested his whole life in marketing his inventions and no time what so ever with his little girl, played by Camilla Belle, or his ex wife Lorraine played by Virginia Madsen.
When Axle gets out of prison not only is his name poison with the large retail giants, but his ex wife has remarried to a Forest Ranger named Jerry King played by Craig Robinson, and they have slowly squandered a fortune of over 200 million dollars. Axle's only daughter Claire, played by Camilla Belle still suffers from latent child abandonment issues. So life has been cruel to Robert Axle these past 10 years in prison. He first befriends his daughters two roommates, who agree to give up their couch to Robert rather than have to watch him live in a men's shelter for too long.
In an effort to redeem himself and regain his Midas touch with a new invention, Axle goes to work at the fourth largest retail chain named Family World, whose immediate Assistant Store Manager is a guy named Troy Coangelo, played superbly by Johnny Knoxville. Axle and Troy don't see eye to eye on the store's priorities and as such Axle's career at Family World is short lived. Desperate to make amends with his daughter Claire, Axle does come up with a new invention but can't find an investor willing to risk financing a dead beat and felony ex convict like Axle.
Eventually he does find one investor and he also makes amends with his daughter. Yes, there are a few sentimental tear jerker scenes between father and daughter but not quite enough good film value for me to recommend Father Of Invention for your viewing pleasure.
As a result I rate the film a 5 out of 10. Viewer beware of a weak script with little decent content.
