Michael Gambon, Leslie Bibb, Colm Meaney and Theresa Randle have boarded the Film Department thriller Law Abiding Citizen. They join previously cast Gerard Butler and Jamie Foxx in the F. Gary Gray-directed vigilante movie.

According to The Hollywood Reporter, The Longest Yard screenwriter Sheldon Turner recently came on to do production work on the script as the film chugs toward its Jan. 21 start date in Philadelphia.

Law Abiding Citizen is set in motion when a district attorney orchestrates a plea bargain that sets free the killers of another man's family. The aggrieved victim then seeks personal justice from the D.A.

Writers Kurt Wimmer (The Recruit), David Ayer (Harsh Times) and Frank Darabont (The Mist), who was once in line to direct Law Abiding Citizen, have worked on the script.

Production begins Jan. 21 in Philadelphia.
