Meanwhile, the manager of the BellRock hotel said a number of bookings have been cancelled and that was of concern as business "just ticked over" outside the tourism season.
"Black Rock, " follows three childhood friends, played by Kate Bosworth, Lake Bell and Ms. Aselton, as they head out to a remote island for a girls reunion weekend.
"If you throw a rock in this town you are going to hit an industry executive, " said Lake Bell, the writer, director and star of "In a World, " which will be shown at the festival.
