The clip is very brief, but is nonetheless impressive and gives a sense of what Dominik's doing with the crime-saga source material. It plays in one shot as a thoroughly annoyed Sam Shepard pays a visit to a perplexed Ray Liotta, who continues to be perplexed even as he's tossed about like a ragdoll. The way the camera captures what's happening is impressive and really pretty funny, but it's also slow and deliberate enough not to be show-offy.
For context, Killing Them Softly is adapted from the novel Cogan's Trade by George V. Higgins. The story follows Jackie Cogan, a professional enforcer, who is tasked with investigating a heist that bamboozled the mafia during a high stakes poker game that was meant to be protected. Since Cogan's an enforcer, you can imagine what he's meant to do when he finds the responsible parties.
Brad Pitt reunites with his Jesse James director here, starring as Cogan. The supporting casts includes Sam Shepard, Ray Liotta, and Slaine, all of whom you see above, as well as Garret Dillahunt, Richard Jenkins, Max Casella, James Gandolfini, Ben Mendelsohn, and Linara Washington.
