Warner Bros. Pictures is reported to indeed develop "The Departed" as a trilogy with the second script telling a continuation to the story presented in the movie.
Adding the hype of the recent publication on the sequel to "The Departed", CinemaBlend.com has pointed out that Warner Bros. Pictures is indeed aiming to make the mob saga a trilogy as Mark Wahlberg previously indicated last month.
"(Screenwriter) William Monahan isn't just writing a second movie, he's also working on an outline for a third Departed film. What either movie will be about is still anyone's guess," the site stated.
Furthermore, the site also informed that the script for the second installment that Monahan is currently penning positively will center on Wahlberg's character Dignam and so, leads to a conclusion that the project will not be a prequel as presented in the original version, which was a Hong Kong production.
