Tony Scott Signs Up for Drug Drama 'Narco Sub'

Tony Scott has signed up to direct the upcoming drug drama Narco Sub.

The film, written by David Guggenheim, concentrations on the ways in which South American drug cartels smuggle cocaine into the United States ... under water.

It won't be the first such film for Scott, who superbly attempted underwater with 1995'sCrimson Tide. Ridley Scott's brother most freshly helmed last year's Unstoppable, and was in August in talks to remake The Wild Bunch.
