Spacey plays Robert Axle an arrogant infomercial tycoon who's built a billion dollar empire by not really inventing products - he fabricates them. The guy's a genius at taking things others have successfully made and COMBINING them with other products...like the combo weed-eater-sand-wedge, digital camera-pepper spray protection device...and too many more to count.
His meteoric success is derailed when one of his products - a combo ab-cruncher-remote-control - is caught up in a product safety suit (the device works, but it inadvertently chops off fingers) and he's sent to federal prison. Time passes and 10 years later he's released and back on the streets.
Axle's only problem is that his wife (Sideways' Virginia Madsen) has divorced him, taken his fortune and remarried to Craig Robinson (The Office). Oh, and his daughter (Camilla Belle) hates him enough to change her name and move into a rent house with a man-hating lesbian (Heather Graham).
His crime, other than making a product that deletes digits, is that he destroyed his family by spending so much time building his business. Axle was an absentee father and after 10 years in the slammer, they'd just as soon he didn't reappear.
Spacey's mission, should he decide to accept it, is to reconnect with his estranged family, rebuild his career and reinvent himself to the business world. In the hands of lesser talent, this could easily turn into a clichéd mess, but two-time Oscar winner Spacey strikes just the right balance with humor and honesty.
His road to redemption is a lot of fun to watch as it sprints (it clocks in at a tidy 93 minutes) to its almost-Hollywood finish. A supporting cast that includes John Stamos and Johnny Knoxville (Spoiler Alert - he doesn't get hit in the nuts one time) is just the icing on the infomercial.
At its core, Father of Invention is a funny, slightly sweet story about the power of forgiveness - which is arguably the greatest invention of all.
