Shot in Georgetown two years ago, "The Bay", a sci-fi thriller were parasites get into the water supply and threaten to wipe out the population, is set to open in theaters on November 2, 2012.

Here's a little on the movie from the film festival website:

The quaint seaside town of Claridge is buzzing with a street fair, crab-eating contests, fresh apple pies, and bathers frolicking on the waterfront as the residents prepare for their annual Fourth of July celebrations. In Claridge, water is the lifeblood of the community. But when two biological researchers find a staggering level of toxicity in the bay, no one is prepared for the horrors that lurk below the surface.
