Robert De Niro has left GK Films' "Edge of Darkness" due to "creative differences" reports Variety.

De Niro had just arrived on the Massachusetts set of the Martin Campbell-directed drama this week and had signed to play an operative sent to clean up the evidence in the murder of a young woman.

Mel Gibson stars as the victim's father, a homicide detective for the Boston Police Dept. who uncovers her secret life, a corporate cover-up and government collusion. Danny Huston, Shawn Roberts and Bojana Novakovic also star.

The filmmakers plan to shoot around De Niro's character's scenes until they cast an actor to replace him. Shooting had been underway since August 18th.
