I have had a look at academic research one of the book i have had a look at is 

Brode, Douglas (1995)

Money, Women,  and Guns 

Carol publishing group 

New York

In this book i found a chapter on Bonnie and Clyde, and how this was one of the first ever film that changed the way the crime genre was portrayed. Also how within the story that begin they create a love romance  and from here we see the crime genre kike in to the film and see all the action of guns and robbery and also them together create mayhem.
