Traveling theory not only asks questions about applicability, but also discusses adaptability. The traditional Actantial Model is not applicable when explaining Genets Maid, but back to the origin of semiotics of theatre, it can be found that for postmodern drama, it is not the structural analysis of binary opposition that is not applicable, but the elements of binary opposition have changed, where in turns syntax and grammar need to be corrected. If Actantial Model wants to break through its explanatory power, it must innovate tools. The new Actantial Model is still composed of three sets of binary antagonistic elements, the sender and receiver, the subject and object are unchanged, the auxiliary body and the opposition body are changed to the constructive body and the deconstructive body, and their relationship is no longer connected by one-way or two-way arrows, but replaced by three related hyperbolas, which are infinite and nonlinear.Using it to analyze Maid and The Life of Pi, it shows that Actantial Model is quite adaptable to postmodern drama and even new film works.
