Taylor Swift released a behind-the-scenes look at how she filmed the most bizarre part of her “Look At What You Made Me Do” music video. The video shows the pop star meeting and greeting dozens of her stunt doubles as they prepare to shoot sequences in front of a green screen, where all of the Taylors fall off a “Taylor Mountain.” The doubles are all dressed in past iconic outfits Swift has worn from music videos and events. “OK, this is the trippiest thing I've ever seen in my life," Swift says at the start of the video. "Seeing all of them together is the weirdest feeling, but it's awesome. It's like, 'Oh, that's the phase I went through when I was 16 but a girl is wearing it who looks just like me.”
