Nicole previously opened up about taking on the role.
"He [director James Wan] is a really good friend of mine and he offered to let me play Queen Atlanna," she told Entertainment Weekly.
"As soon as he said I could wear mother-of-pearl and be a mermaid warrior, I said, 'I'm done. Please. If there is one thing I have to do in my life, I have to be that.' Because you’ve got to have some fun."
Nicole filmed most of her scenes at Hastings Point's Curry Lighthouse in New South Wales in August 2017.
