As the NBA’s most winningest and most storied franchise, there is no paucity of documentaries about the Boston Celtics. In fact, quite the opposite — one could seemingly fill weeks of time watching just the better-known stabs at putting the history of the team into a video format. But there is a new contender on the scene in that regard, and we are not referring to NBA titles here, or at least directly. The Ringer’s Bill Simmons and HBO have teamed up to bring the world “Celtics City,” a new documentary series that aims about as high as one can with these things. The Celtics Wire recently sat down with the director, Lauren Stowell, and co-executive producer and showrunner Gabe Honig to talk about the new docuseries and what sets it apart in a sea of similar content. To that question in particular, Stowell was forthright in her reply. “This one is the definitive complete story, not told in bits and pieces or your favorite iconic moments or eras,” she explained. “We’re starting from Red Auerbach getting the job and Walter A. Brown owning the team through Banner 18, and the journey to that.”
