Zack Sharf Digital News Director Becoming princess Ariel for Disney’s live action “The Little Mermaid” required Halle Bailey to be in the water for 13 hours straight on set during some days of filming, the actor revealed in a new Edition magazine profile. The film, directed by “Chicago” and “Into the Woods” helmer Rob Marshall, used practical water tanks and visual effects to create extensive underwater sequences for the movie. “I pushed myself as far as I’ve ever pushed myself in life,” Bailey told the publication about spending some days on set in the water for 13 hours. “And I feel like the message from [Ariel] was to know that you’ve always had it in you.”
