Sherry Lansing is one of the last great Hollywood producers. Rising up through the ranks, from actress to script reader to head of Paramount pictures, her career spans the time when Hollywood went from stodgy and insular to wild and brash and into corporate-run risk-averse number counters. Through her time in charge, she led projects near to her, stepped down on her own terms, and led a life of philanthropy. Definitely worth the read.
