Sam Wasson: 'The Big Goodbye'

In author and cultural historian Sam Wasson's new book, 'The Big Goodbye', he tells us that the 1970s ended in Hollywood in 1974, with the release of the epochal film 'Chinatown'. He takes us inside the chaotic and creative environment that brought screenwriter Robert Towne, director Roman Polanski, studio chief Robert Evans and star Jack Nicholson together -- a once in a lifetime union.
