At the beginning of the film, one hand skillfully drew several butterflies. It's the protagonist Victor. In the transparent glass cover in front of him, the blue butterfly has been dancing. The camera is opened from the back, and many pictures of butterflies have been posted on the wall by the window. Victor pushed open the window and opened the glass cover. The music suddenly became strong and butterflies flew out. The title of this film is: Corpse Bride. This forms an obvious correspondence, and the butterfly corresponds to Corpse Bride. Therefore, although the humanoid corpse bride appeared in the film after 17 minutes, which obviously violated the usual drama rules, in fact, this character element appeared in the first scene, that is, the butterfly. If it can't be confirmed and recognized, then a more obvious example is that, finally, Corpse Bride walked out of the church and headed for the moonlit night. The evening breeze blew her wedding dress, and Corpse Bride turned into a butterfly and flew away. From beginning to end, the butterfly truly represents this Corpse Bride. Various plots and occasions that follow the appearance of butterflies. Flying out of the glass cover, the butterfly turned around Victor and flew out of the window. From the beginning, it was suggested that Victor and Butterfly had an indissoluble bond. Victor likes butterflies, paintings on the wall, skillful brushwork, opening the glass cover carefully and watching butterflies fly happily. The butterfly is attached to Victor. The fate of Victor and Corpse Bride has long been buried here. Before Victor talked to Victoria, before he fell in love with Victoria, he had told countless secrets to butterflies, and he had fallen in love with butterflies. Butterflies are flying in the street. The camera follows the trajectory of butterflies, leading the audience to appreciate this Victorian town, which is calm, dull, indifferent and closed. Fishermen, old gentlemen, old women and bell ringers are spreading news. Then, a stranger appeared. He doesn't belong in this town. He is a dangerous man. He waved the butterfly away in disgust, just as he viciously killed and abandoned Emily, making her a "Corpse Bride". This action between the butterfly and the baron is a hint. The last scene reveals that the Baron is the murderer of Corpse Bride. These are not all my opinions, and some are for reference only (* _ *).
