Zack Sharf Sia revealed to The New York Times as part of a profile on comedian Kathy Griffin that she entered rehab following the extreme outrage over her feature directorial debut, “Music.” Sia sparked backlash over her decision to cast neurotypical actress and dancer Maddie Ziegler in the lead role of Music Gamble, a nonverbal autistic teenage girl. Ziegler and Sia had previously worked together on the musician’s videos for “Chandelier” and “Elastic Heart.” Several members of the autism community condemned “Music” over Zeigler’s casting and the portrayal of autism in the movie.
