Full of surprises and insights, More Than Cowboys casts new and entertaining light on the history and personalities of the American West. For example, was Butch Cassidy really killed in a Bolivian shoot-out? It seems that he returned, under a false name, to live out his days in the West. In 1935 he even submitted an autobiographical script to Hollywood, only to have it rejected as being "too preposterous to be believable.".
