Entertaining bio (but then most bios of Flynn are), the 2 lives apparently are that Flynn lived the equivalent of (at least) two lives. Obviously I have no idea how much of this book is true. The Chapter titles are from names of his movies, kind of how they pertain to his life.
This is a biography by a man who reads other biography. Very little in here was not covered in My Wicked Wicked Ways by Flynn himself (and ghostwriter). And the picture of Sean Flynn in the car on the way to the funeral is just tacky.
