Who the Hell's In It? stars Cary Grant, Jimmy Stewart, James Cagney, Bogart, Bacall, Brando, Chaplin, Audrey Hepburn, Sinatra, Dean Martin, Jerry Lewis, John Wayne - among many others. The book begins with Lillian Gish - the first film star - and ends with Marilyn Monroe, whose death coincided with the demise of the studio system that created the film stars. Bogdanovich captures - in their own words and his - what made them who they were and what gave them their appeal. The fact that Bogdanovich knew most of the stars he interviews gives the collection a poignancy and authenticity.
