The film is apt to be somewhat fun to watch for anyone familiar with Troy, Rensselaer County, New York, though likely far slower and artier than the average viewer is apt to enjoy. There are lots of local businesses that appear, and roads that are recognizable like Hoosick Road, Oakwood Avenue and probably Farrell Road. The geography is a little confusing when it comes to the Lake George references. Lake George is more than a little than "just outside of Troy" as it's described - it's about an hour's drive north and two counties away.
The Helen statue's head that's seen floating along - that's not in Lake George as some viewers interpret it, but in the Hudson River that runs along the west side of the City of Troy.
The story? You're best off turning to interviews of the directors online. Childhood readings of Greek mythology, not revisited, contributed as well as some real-life things abut which they'd read, further influenced by the eventual choice of Troy as the primary shooting location.
