The Luther star, who plays Alice Morgan in the BBC crime drama, is in talks to appear in Scott Frank's crime thriller with Milk actor Boyd Holbrook, reported Variety.
Liam is already set to play private investigator Matthew Scudder, who is hired by a drug lord to discover who kidnapped him and murdered his wife.
Downton Abbey's Dan Stevens was the latest addition to the big-screen adaptation of Lawrence Block's novel.
A Walk Among The Tombstones is due to begin filming in March.
Surrey-born actress Ruth, who was last seen in Joe Wright's Anna Karenina, will next appear in Gore Verbinski's The Lone Ranger alongside Johnny Depp and Armie Harmer.
