There’s even another Rocky movie titled I Play Rocky coming out in November. A new book by Philadelphia Inquirer sports columnist Mike Sielski offers a behind-the-scenes look at the first Rocky film. I really think it’s the first and definitive telling of the story behind the making of the movie. If you’re interested in a piece of sociological history and storytelling about Philadelphia, I think the book is a great look at what Philadelphia was back at that time.
