Robert De Niro just arrived on the set of Edge of Darkness this week. Then, he bowed out and left the production.

De Niro planned on playing 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 find outs about her secret life, a corporate cover-up and government secret plot.

Danny Huston, Shawn Roberts and Bojana Novakovic also star.

The filmmakers plan to shoot around De Niro’s character’s scenes pending a replacement.
