Tucker: the Man and His Dream (1988)

Based on a true story. Shortly after World War II, Preston Tucker is a grandiose schemer with a new dream, to produce the best cars ever made. With the assistance of Abe Karatz and some impressive salesmanship on his own part, he obtains funding and begins to build his factory. The whole movie also has many parallels with director Coppola's own efforts to build a new movie studio of his own.
