Los Angeles-based Bold Films is developing an untitled legal thriller with James Mangold and Cathy Konrad's Treeline Films in the vein of The Verdict and All The President's Men.

Mangold is attached to direct the true story of a pair of New Orleans lawyer brothers who take on Big Oil and uncover the truth behind a fatal rig collapse.

Bold's president of worldwide distribution Stephanie Denton and executive vice president of international sales Jim Harvey represent worldwide rights at EFM.

After flying to New Orleans to obtain life rights, screenwriters Sasha Jenson and Casey La Scala attached Mangold and brought the project to Bold Films.

Bold Films owner Michel Litvak and co-president David Lancaster will produce and co-president Gary Michael Walters takes an executive producer credit with La Scala.
