The film “The Knot” revised from literature play “Looking For” uses timespace intertwining method, traces the emotion of “looking for”, and extends the single loving theme into the unity of loving and the unification of the motherland. Although the splendid use of Montage method and overall application of DI (digital intermediate) technology successfully solve the ideological orientation of the theme of the film and the operation model of the audiovisual expression of a commercialized film or a drama, excessive flashback and lens switching as well as the inclusion and combination of various movie types make this film not only look in a mess but also weaken its vicissitude feeling to make this film wear the coat of a mandarin duck and a butterfly.
