The production company for the movie "Big Shark", which was filmed in Downtown Lafayette, has released the trailer.  (CAUTION: NSFW Language)

Judging by the trailer, the film is about a downtown area experiencing some flooding, and a large (big, if you will) shark infests those waters, preying on unsuspecting people.

As of this posting, the "Big Shark" movie website redirects to star/director Tommy Wiseau's merch page.
