Hannibal is the fictional opera performed at the beginning of the 1986 musical. According to the poster, this opera's music is supposedly composed by Chalumeau. Not much is know about the actual plot except that it tells of the return of troops from fighting against Roman soldiers. During the rehearsal for Hannibal, a piece of scenery falls on Carlotta Giudicelli, the leading soprano at the Opera Populaire, and she refuses to sing the song "Think of Me". The managers of the Opera, Andre and Firmin, have Christine Daaé sing it. She is chosen as the leading soprano for the evening, and the play is considered a triumph.
