Underwater dangers seem to be back in demand these days (movie-wise, that is). We had Piranha 3D earlier this month, along with its proposed sequel in development, and now news hits that Shark Night 3-D is moving forward in production. Those unfamiliar with the project might ask, “Who would be directing a film called Shark Night 3-D?” Well, it’s none other than Snakes on a Plane director David Ellis. With a resume that also includes two of the Final Destination films, Ellis certainly has a handle on creative deaths and gore, which makes him a perfect fit for the material.

Casting for the film has already begun as several of the lead actors have been announced. Sinqua Walls (Friday Night Lights), Chris Carmack (The Butterfly Effect 3: Revelations), Alyssa Diaz (Red Dawn), and Joel David Moore (Avatar) will play some of the young men and women who “spend a weekend at a lake house in Louisiana’s Gulf area.” Things take a turn for the worse when the group begins falling victim to shark attacks. That’s right, sharks in a freshwater lake. “They soon discover that the sharks are part of a sick, greedy plan on the part of several locals.”

Wow, that plotline sounds like a dark version of a Scooby-Doo episode, which could be a lot of fun. I enjoyed Snakes on a Plane for what it was, so hopefully Ellis can bring that same sensibility to Shark Night 3-D. The production starts in September and features a script by first-time screenwriters Jesse Studenberg and Will Hayes. What do you think? Could we use some more underwater terror in theaters?
