Just one day after Downton Abbey's Dan Stevens joined the cast of A Walk Among the Tombstones, Luther star Ruth Wilson has also signed on to star.

Liam Neeson stars as a former NYPD cop who now runs his own private investigation firm, where he operates just outside the law to get results for his clients. He is hired by a drug dealer to find his kidnapped wife, which leads him to a dangerous crime ring lead by perpetrators who have committed multiple kidnappings and murders. No details were revealed for Ruth Wilson's character.

Scott Frank is directing from his own adapted screenplay, based on the Lawrence Block novel, with Michael Shamberg, Stacey Sher, and Danny DeVito producing. Universal Pictures will distribute, with Exclusive Media Group and Cross Creek Pictures financing. No production schedule was given.

Aside from her role as Alice Morgan on Luther, Ruth Wilson recently starred in Anna Karenina last year. She also has major roles in Disney's The Lone Ranger and Saving Mr. Banks, both slated for release later this year.
