The movie poster uses a subdued color palette with red as the only bold color to draw attention to the striking title. Reviews from respected sources indicate it is a well-directed, sophisticated thriller appealing to audiences who like to think critically. Gary Oldman's name is the largest to signal he is the main figure, and the actors avoid eye contact, adding an air of secrecy and suspicion. Images of a man with a gun and in a library setting imply themes of violence and intellectual stimulation.
