Martin Campbell will direct the feature adaptation of the six-hour 1985 BBC miniseries, which Campbell also directed, Variety reported Tuesday.
Gibson will play a police investigator whose activist daughter is killed. As the character delves deeper into the case, he uncovers systemic corruption that led to his daughter's death.
Gibson's last feature roles were "Signs" and "We Were Soldiers," spending intervening years as a director, first on "The Passion of the Christ" in 2004 and then "Apocalypto" in 2006.
Monahan and King also are collaborating on a bio-pic of Jim Keene, who traded a prison sentence to go undercover at a maximum security hospital for the criminally insane, Variety reported.
