Huston, Roberts and Novakovic added to thriller
GK Films is financing.
"Darkness" centers on a veteran cop (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 takes on the role of a shady businessman while Roberts will play the role of the daughter's distraught boyfriend.
Robert De Niro is also in the film, cast as a CIA cleaner.
Lensing is due to start later this month on location in Massachusetts. William Monahan and Andrew Bovell wrote the screenplay.

Serbian born and Ozzie-raised Novakovic, repped by CAA and Management 360, will be seen in Sam Raimi's "Drag Me to Hell" as well as the Will Smith-starrer "Seven Pounds."
Canadian Roberts recently completed filming a lead role in Fox Atomic's "I Love You, Beth Cooper" for Chris Columbus and appeared in "George A. Romero's Diary of the Dead." He is repped by Gersh, Characters Talent, and Wright Entertainment.
