Dermot Mulroney is trading Chicago for the wild West in Long Shadows, and ScreenRant has an exclusive look at the first trailer for the project. William Shockley, who is best known for playing Hank Lawson in the long-running Dr. Quinn, Medicine Woman, is making his directorial debut — adding a sense of authenticity to the proceedings. The film arrives in theaters on September 26 after Quiver Distribution acquired the North American distribution rights.
