Carlotta Guidicelli and Ubaldo Piangi

Carlotta is the Prima Donna of the Opera House. During the rehearsal of 'Hannibal' a piece of scenery almost falls on top of her, prompting her to leave. She later returns after Christine's great triumph in her role, and demands that she have the lead role in 'Il Muto'. The managers let her sing the lead, going against the wishes of The Phantom, who wants Christine in the role. During the performance, Carlotta blames Christine for the interruption, and calls her a little toad, to which the Phantom replies "A toad Madame? Perhaps it is you who are the toad?" After this Carlotta attempts to sing, but emits a toad like croaking noise! She tries again to sing, but is unsuccessful, and so leaves the stage crying.
When The Phantom insists that they perform his opera, 'Don Juan Triumphant', Carlotta is given a small role, which she is resentful about. She blames Christine and accuses her of orchestrating the whole thing, just to get the lead role. During the rehearsal she cries "No-one will know if it is right or if it is wrong, no-one will care if it is right or if it is wrong!" when Piangi gets the phrase wrong. When Piangi is murdered during the actual performance, she breaks down crying and blames Andre and Firmin for the 'accident'.
The original Carlotta was played by Rosemary Ashe.
