Robert De Niro was originally cast as Darius Jedburgh, but dropped out due to creative differences after a few days on the set.
Based on the popular, award-winning British television miniseries Edge of Darkness (1985), written by Troy Kennedy Martin, and directed by Martin Campbell. In the original, Bob Peck played Craven, and Joe Don Baker played Darius Jedburgh.
The character Jedburgh is a British-accented secret operative of some sort. "Jedburgh" was also the name of a well-known British WWII program whereby they covertly inserted 3-agent teams, called "Jedburgh Teams," of covert Allied operators into Nazi-occupied France.
Joe Don Baker, who starred in the miniseries on which this film is based, and was a friend of director Martin Campbell, was reportedly against the idea of this film, feeling that a single film would not be able to capture the essence, story, and weight of the original series, and do it justice.
