I dont know if any movie or book will be descriptive as what the trial brought out of people. I mean I heard the black mass was very good. I mean if they wanted to make a movie that would be epic. I would first start by doing the whole movie in southie not just small clips because woburn and danvers is no fucking southie by a longshot. Second I would use the book and any other book to get a idea, perspective and take pieces from it. I wouldve paid, Martorano,weeks, shea, even whitey and flemmi, connoly themselves or any other character like winter or Pat Nee. That way the movie would be very authentic. My opinion but as a Bostonian, I was upset they didnt do majority of the movie in Southie.
