Miss Americana was met with a standing ovation at the film festival, as seen in a clip shared by Variety.
The documentary charts Swift’s career and personal life over the past few years, and will be released in selected cinemas and on Netflix on Friday January 31.
Critics have heaped praise on the documentary, with Adam Chitwood of Collider calling it “a fascinating and candid story of how an insanely famous artist who was trained to be nice and inoffensive reconciles her growth as a political and feminist human being in the public eye.”
Decider’s Anna Menta said that while Taylor Swift fans are bound to love Miss Americana, “I also think this film is going to sway some haters.”
HuffPost’s Leigh Blickley called the film “intimate and funny and sad and poignant”.
Variety’s Ramin Setoodeh said it was an “illuminating, empowering portrait of Taylor Swift at a turning point in her career.”
Other critics echoed the praise, with Slash Film’s Chris Evangelista branding it a “dynamite crowd pleaser” and Entertainment Weekly’s Leah Greenblatt saying it was “the kind of insight you actually want into a superstar.”
Miss Americana is directed by Lana Wilson, who made the acclaimed documentaries After Tiller (2013) and The Departure (2017).
The documentary looks at Swift’s journey to becoming politically outspoken, and reveals candid details about her struggles with an eating disorder.
