Christophe Herreros will return to Boothbay Harbor in late March focused on scouting shooting locations for his new film project. Herreros and his film crew were in Boothbay Harbor from Paris in October 2016 filming “Return to Cabot Cove” at the Congregational Church here, Boothbay Harbor Memorial Library and Blue Heron Seaside Inn, among other locations.

Two summers ago, Herreros came back for a vacation with his wife Charlotte DuFranc, his assistant on the Cabot Cove project, and their daughter Anna. They caught up with friends they’d made during that 2016 production and introduced them to their little one. But the visit served a dual purpose: Herreros was checking out the area for another project he had begun drafting with this region in mind.

That project, tentatively entitled “After the Fog,” is ready for filming. Filmmaker/writer/videographer Herreros has been reworking the script over the past few years, a script DuFranc describes as “more precisely written,’ which has fine-tuned the locations Herreros needs for the story.

What’s it about? Well, all we can say with certainty is Jessica Fletcher isn’t one of the characters. DuFranc, translating for her husband, said: “It is a documentary about Boothbay Harbor, a portrait of the area told by the people living and working there.”

Some locations of interest for Herreros when he arrives later next month include Boothbay Railway Village, Burnt Island Light and Boothbay Region Land Trust preserves. Herreros hopes to find a boat and captain to reach some locations under consideration.

The project has been funded through the National Center Cinema or Cinema Graphics Center. “It is the hardest grant to get in France; it is most coveted,” explained DuFranc.

The 10- to 12-member film crew arrives in April with the shooting scheduled for the week of April 17-23.
