Edge of Darkness

In this drama, directed by Martin Campbell, Gibson plays homicide detective Thomas Craven. As he investigates the death of his activist daughter, he uncovers not only her secret life, but a corporate cover-up and government collusion that attracts an agent tasked with cleaning up the evidence. Co-starring Ray Winstone and Danny Huston.

The stress, the traumatic experience of losing a child like that, has him just a little unhinged and walking around most of the time in a state of near breakdown. He is close–right at the edge–but he can’t let it crack too much because he’s got a job to do.
