The Hamptons International Film Festival is known primarily for its annual four-day showcase event held in October. Yet for many years, the festival has spread out its calendar to include summer screenings of documentaries and narrative films, projects in the local schools, and a springtime screenwriters lab. The latter brings established professionals to East Hampton to work with writers early in their careers and bring scripts to fruition, with four in recent years making it to production and, in some cases, winning awards.
