This Sia Movie News Will Make You Swing From The Chandeliers

She also wrote a song for Adele, but now she's keeping it.

It's no secret that Sia is seriously camera-shy. The "Chandelier" singer who pretty much always covers her face in public, has found the perfect answer to her lens aversion: getting behind it.

According to the Hollywood Reporter, Sia revealed during the Venice Film Festival this weekend that she is preparing to write and direct her big screen debut, "Sister."

Wearing her trademark eye-covering blonde wig, Sia told reporters that she's prepping a movie that will star her mini-me, 12-year-old dance diva Maddie Ziegler. "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," Sia said about the movie that is based on a one-page short story she wrote 8 years ago. "And then last year after I made the 'Chandelier' video, I realized that I was pretty good at directing, so I felt a little bit braver."

After striking out with her first pass at a fleshed-out story she wrote with "a guy from a juice bar" who went to film school, Sia tapped children's author and friend Dallas Clayton for help shaping her first script. "He and I spent three-and-a-half weeks just on a sofa, mapping it out," she said. Clayton would take Sia's dialogue and notes and clean them up and then the singer would hand the reworked script over to friends for feedback.

Among the people who've eyeballed it so far: comedian Whitney Cummings, actor Joel Edgerton and her husband, director Erik Anders Lang, who, apparently, gave her the "best" notes.

With music still on the front-burner, Sia reportedly told a Slovenian news outlet that she had originally offered the upcoming first single from her next album, "Alive," to Adele, but that the singer rejected the song at the last minute. "Alive" is due out on Sept. 26 as the first taste of her upcoming This Is Acting album (see what she did there?).

The title is not based on her new job, though, but on the idea that the songs on the album were written for other people, "so I didn't go into it thinking, 'This is something I would say.' It's more like play-acting. It's fun."
