Sia Making New Movie With Video Dancer Maddie Ziegler

The Chandelier singer revealed she wrote the screenplay for Sister eight years ago while chatting to reporters at the Venice Film Festival in Italy over the weekend (05-06Sep15), and now she will direct the film with the young star of her videos.

Sia said, "I was too embarrassed to tell anyone I wanted to make a movie, because I thought it would be seen as a vanity project, because I was a singer... and then last year after I made the Chandelier video, I realised that I was pretty good at directing, so I felt a little bit braver."

The pop star turned to children's book author Dalles Clayton to help her complete the screenplay, adding, "He and I spent three-and-a-half weeks just on the sofa, mapping it out."

She then asked five friends, including comedienne Whitney Cummings and actor/director Joel Edgerton, to give her feedback before deciding to make a start on the project.

Sia isn't the only member of her family making a new movie - her husband Erik Anders Lang is working on a documentary about the game of golf after a crowdfunding campaign helped him raise $50,000 (£31,000) towards filming costs.
