performed as a proxy for Sia in bobbed blonde wigs similar to Sia's familiar hairstyle. The three videos have received a total of more than 4 billion views on Vevo. Sia explained to Kristen Wiig in an interview in Interview magazine that she decided to conceal her face to avoid a celebrity lifestyle and maintain some privacy: "I'm trying to have some control over my image. And I'm allowed to maintain some modicum of privacy. But also I would like not to be picked apart or for people to observe when I put on ten pounds or take off ten pounds or I have a hair extension out of place or my fake tan is botched. Most people don't have to be under that pressure, and I'd like to be one of them." The video for Elastic Heart "courted controversy and plaudits in equal measure", with some commentators perceiving it to have paedophilic undertones due to the relative ages of the dancers. Sia explained that the two dancers represented "warring 'Sia' self states", but she nevertheless apologised on Twitter to anyone who was "triggered". Gia Kourlas wrote in The New York Times in 2016 that Sia's collaborations with Heffington have "done more to raise the standards of dance in pop music than nearly any current artist integrating the forms". The "Chandelier" video was ranked as the 10th "greatest music video" of the 2010s by Billboard. In 2014, Sia contributed to the soundtrack to the 2014 film adaptation of the Broadway musical Annie. Sia, along with producer Greg Kurstin, wrote three new songs for the film as well as re-working songs from the musical. Sia, Kurstin and the film's director Will Gluck were nominated for Best Original Song at the 72nd Golden Globe Awards for "Opportunity". 2015–2017: This Is Acting In an interview with NME in February 2015, Sia revealed that she had completed the follow-up to 1000 Forms of Fear, entitled This Is Acting. The album was another collaboration with producer and co-writer Greg Kurstin. Furler said that she released 1000 Forms of Fear to free herself from her record deal and had planned simply to write for other artists, but the album's success spurred her to continue writing her own music. The same month, alongside the digital deluxe release of 1000 Forms of Fear, she released a mobile game, Bob Job. "Alive" from This Is Acting was co-written by
