Oscar-nominee Viola Davis has joined F. Gary Gray's upcoming thriller "Law Abiding Citizen."

The film, which just recently started shooting, follows a successful assistant D.A. who finds himself at the center of a vigilante plot hatched by a traumatized victim of the legal system.

After finding out that one of his wife and daughter’s murderers will be set free via a plea bargain, Butler’s character decides to take revenge against those responsible for the murders and the deal.

Gerard Butler, Jamie Foxx, Michael Gambon, Leslie Bibb, Colm Meaney and Theresa Randle also on board.

Frank Darabont was originally attached to directed the project, but he bowed out and worked on the script with Kurt Wimmer and David Ayer instead. Sheldon Turner recently boarded the project to do some rewriting.

Davis most recently scored an Oscar nomination for her role in "Doubt." She also recently starred in "Nights in Rodanthe."
