Mankind is always trapped in the introspection in one’s identity and the relationship with others, about which, many philosophers and psychologists like Feud and Lacan, have established various theories. Many science fiction movies can function as allegorical stories for the interpretation of those theories about the two concepts and their relation. Deep probing and comprehensive analyses of those movies in light of Feud’s and Lacan’s theories about the “ego” and the “other” make it easy to see that the “ego” has an intricating relation with the “other”, which symbolizes both other people, the world and the ego itself. The “other” is intimidating to the “ego”, but the integrity with it is also what the ego pursuits. So, for the harmony between the “ego” and the “other”, the “ego” should pursuit its integrity with the “other”, while confirming its own identity.
