<P> Filming began on March 3 , 2013 in New York City . Producers invited author Block to the set to watch filming . On the casting of Neeson , Block said , `` Readers often ask who 'd be my ideal Matt Scudder , and I usually change the subject . But now it 's safe to tell you that , ever since I saw him in Michael Collins , Neeson has been up at the top of my personal Scudder wish list . I could n't be happier about either the star or the writer / director , both of them genuine artists and brilliant professionals . My book 's in good hands . '' </P>
