It all started with Sabrina!

Epstein, Edward Z.  Audrey and Bill: A Romantic Biography of Audrey Hepburn & William 
       Holden.  Philadelphia, PA: Running Press, 2015.  ISBN: 978-0-7624-5597-3

The Introduction to Audrey and Bill clues in the discerning reader that Epstein is providing a biography of the "romance" of Audrey Hepburn and Bill Holden rather than a complete biography of their entwined lives.  Epstein using published accounts and interviews then proceeds to document how their shared connection affected the rest of their lives.

The movie Sabrina served as the catalyst for bringing Audrey and Bill into each others lives.  Some of the romance played by their characters bled into real life, or maybe it was the other way around.  And as in the movie, Bill did not get Audrey in the end.  But that fact did not end the connection between the two.  Epstein takes sixteen more chapters to tell how Audrey and Bill found other arms to comfort and support them.  They even worked together on another movie, but the spark found in Sabrina could not be flamed back to again as too much time and experience had shaped each of them. 

Epstein wrote a very readable account of the entwined lives of Audrey and Bill, providing plenty of stories, movie details, and glimpses of Hollywood life all through a rose-colored filtered lens of romance.  The book starts with the filming of Sabrina with little backstory on how Bill Holden and Audrey Hepburn arrived at that point in history.  The tale continues through the romantic lives and movies of each person ending with their death, followed by a brief look at their place in movie history.   Audrey and Bill works best for readers interested in the interaction of stars and their movies who do not expect too much analysis on the way.

Scholars on Comic Book Movies

Burke, Liam.  The Comic Book Film Adaption: Exploring Modern Hollywood's Leading Genre. 
        Jackson: University Press of Mississippi, 2015.  ISBN: 9781628462036

Liam Burke brings an academic's focus to the study of comic book movies.  In five chapters, he mines adaption theory in light of comic book film studies, surveys audiences in Ireland regarding their knowledge of comic fandom, studies how the Marvel Way of Comics has influenced comic book movies and many other topics.

Each chapter is self-contained, but mentions discussions found in other chapters.  Chapter titles include The Golden Age of Comic Book Filmmaking, The Comic Book Movie Genre, Fans, Fidelity, and the Grammar of Value, A Comic Aesthetic, How to Adapt Comics the Marvel Way, concluding with The Future of the Comic Book Movie.  Burke also includes in an appendix the North American Box Office Totals for Comic Book Film Adaptions (in dollar amounts not weighted for inflation).

Burke develops well his thesis for each chapter, providing plenty of scholarly detail and notes to other studies.  He makes his points accompanied by illustrations where appropriate, but never really provides a coherent theme or scope for the book.  Rather he seems to have taken ideas that did not make it into published articles and crammed them into one disjointed book.  However, if you are interested in film adaption theory and comic books, you could mine this book for your own pleasure.
