Abstract: As a public and popular form of mass media, films play an important role in cross-cultural communication. With information about the film itself and the foreign culture, subtitles are vital for the audience’s entertainment and furthermore for the success of cultural communication. Therefore, subtitle translation gradually shows up as an important and indispensible social activity. However, due to linguistic and cultural differences, subtitle translation is usually regarded as an interesting but demanding task. The way how to deal with all these factors involved depends on the purpose of the task, for each film is generally introduced to another foreign country with a certain aim, such as entertainment, education or business profits and so on. This paper aims to study the subtitle translation of The Big Bang Theory from the perspective of the skopos theory. On the basis of typical features of this TV series and the general principles of skopos theory, some translation strategies, such as foreignization and domestication are summarized to help readers have a better understanding of subtitle translation and promote the communication between different cultures. 

Key words: skopos theory, subtitle translation, foreignization, domestication
