Miss Atlantis is the Medici Bros. Circus’ resident mermaid who spends much of her time isolated in a tank.


Sharon Rooney was cast to portray the lonely mermaid. “When you first see Miss Atlantis, she’s not the happiest member of the circus family,” says Rooney. “She’s on her own quite a lot and keeps herself apart, like a sad little fish. But as the story grows, so does she, and she starts to come into her own and become part of the family.”

Rooney was tapped to sing the iconic song “Baby Mine” in the film. “It’s such a powerful moment,” says Rooney. “Separating a new mom from her baby is just so awful, and I think the troupe all feel it in their hearts. We made up a backstory for Miss Atlantis — I think as an actress, it’s really important to know why she’s singing what she’s singing. It’s such a powerful song.”

Miss Atlantis’ costume consisted of more than 100 overlapping scales, which were hand stitched. Alternating rows of black and turquoise, the scales were constructed from three to four layers of fabric with sequin borders to give each scale a reflective quality.
