The Negotiator (1998)

This is a noteworthy movie. Hostage negotiator Danny Roman (Samuel L. Jackson) finds his colleague soon after he is shot in his car. Based on circumstantial evidence found at the scene, the police assume Roman is the killer. He suspects the department is involved in a conspiracy to cover up money embezzled from the disability fund, so he takes several hostages to expose the truth. Hoping that an outsider will be more trustworthy, he requests that negotiator Chris Sabian (Kevin Spacey) is brought in to resolve the standoff.

J. T. Walsh who played Inspector Terence Niebaum died of a heart attack five months before the film was released. The building used for the internal affairs office is the headquarters of United Airlines.
