Inventing David Geffen tells the story of a poor kid from Brooklyn who moved to L.A., got a job in the mail room at a prominent talent agency, and feigned his way as an agent. Soon he was on his way to being a multimedia tycoon and political filmmaker, fostering the likes of Jackson Browne and Joni Mitchell, producing films and Broadway shows, cofounding Dreamworks entertainment, and being a major backer for Barack Obama's presidential election. This American Masters entry is a fascinating success story and profile of an incredibly ambitious man, whom most of his friends describe as either assured, difficult, generous, or completely focused. It is very well made and features excellent footage, and in addition to the many celebrities who appear, Geffen himself is interviewed throughout and provides an above board commentary on his life.
