With fresh appraisals of popular Westerns, this book examines the history of the genre with a focus on definitional aspects of canon, adaptation and hybridity. The author covers a range of largely unexplored topics, including the role of "heroines" in a (supposedly) male-oriented system of film production, the function of the celluloid Indians, the transcultural and transnational history of the first spaghetti Western, the construction of femininity and masculinity in the hybrid Westerns of the 1950s, and the new paths of the Western in the 21st century.
