Virginia Madsen has joined the cast of "Father of Invention", the indie comedy from Kevin Spacey's Trigger Street Productions.  Spacey plays a down-on-his-luck inventor turned billionaire-inventor who once again finds himself down on his luck when an invention goes horribly awry - that Slap-Chop was always too good to be true.  Madsen will play Spacey's wife in the film which is being directed by Trent Cooper ("Larry the Cable Guy: Health Inspector").  "Invention" has already begun filming in New Orleans with co-stars Camilla Belle, Heather Graham, Johnny Knoxville and the great Craig Robinson.
