The Hollywood Reporter posts that the wonderful, needs-to-be-in-more-films Danny Huston is signing on to the cast, along with Shawn Roberts (Diary of the Dead) and Bojana Novakovic (Seven Pounds). The Martin Campbell-helmed feature will focus on a veteran cop played by Gibson, "whose only grown-up child (Novakovic) is murdered on the steps of his home. The cop unearths his daughter's secret life and discovers a world of corporate cover-ups and government collusion." Huston is going to be a shady businessman, I presume somehow entangled in this mess, while Roberts will play the boyfriend of the daughter.
With a little Robert De Niro on board to clean up messes, this could be one interesting film.
