IntroductionAs one of Hollywood's most popular directors, Christopher Nolan was known for his complex storyline and non-linear film structure. His most famous works, including The Prestige (2006), Inception (2010), the Batman series (2005, 2008, 2012), many of his works have been nominated for numerous awards. This article mainly analyzes two famous movie posters from his works, The Dark Knight (2008) and Inception (2010). Semiotics, known as the science of meaning, was created by Ferdinand de Saussure and Charles Sanders Peirce. This article will implement semiotic analysis, introduce the theory of semiotics, and review the history in general. Semiotics is the interpretation of meaning, based on the semiological approach of Saussure; he focused primarily on the structure of linguistics, while Peirce focused more on the logical dimensions of science. In general, semiotics is the study of signs. According to Gordon, he defined this sign as “anything that speaks to us about something other than itself” (Gordon, 1996: 14). A sign is a representation of an object or a deep meaning implied behind the object. Saussure developed the principle of semiotics by applying it to language, he also developed the relationship of a sign with the following formula: "signifier + signified = sign" According to Saussure's notion, the signifier is the carrier sign meaning, including the marks on the paper and the sound in the air. The signified is a mental concept of meaning, according to which a person with the same cultural background can share the same language. The sign is embraced by both, making the sign have a wider use. Peirce's idea of ​​semiotics is a statement of meaning, representation, reference and meaning. As the most influential and logical theory in the history of semiotic analysis, Peirce's views on semiotics are compatible with Saussure's theory..
