"As of March I'll be doing 'The Little Mermaid'. I think it's a plethora of things. I'm excited, I'm nervous. I'm just excited to show something that I've loved for such a long time and in a different modern light.
"I'm going to start training underwater in about a month, so we'll see how I am on that. Underwater training?! This is no joke!" Moretz said.
