Variety reports that actress Halle Berry is in talks to play a dive instructor who survives a near-fatal great white shark attack in the upcoming film, "Dark Tide." The article does not mention whether the shark angle is a central part of the plot or not. No word on whether or not a gigantic, fake, rubberized, mechanical shark will be used in the film, which, in turn, could then be used as a pop-culture reference in any news story involving the mention of sharks.
